 * #### block
-One or more expressions and declarations surrounded by curly braces. When the block evaluates, all of its expressions and declarations are processed in order, and then the block returns the value of the last expression as its own value. Blocks are commonly used as the bodies of functions, [for expressions](#for-expression), `while` loops, and any other place where you want to group a number of statements together. More formally, a block is an encapsulation construct for which you can only see side effects and a result value. The curly braces in which you define a class or object do not, therefore, form a block, because fields and methods (which are defined inside those curly braces) are visible from the out-side. Such curly braces form a template.

 A bound variable of an expression is a variable that’s both used and defined inside the expression. For instance, in the function literal expression `(x: Int) => (x, y)`, both variables `x` and `y` are used, but only `x` is bound, because it is defined in the expression as an `Int` and the sole argument to the function described by the expression.

-There's an important difference between the foreach method on iterators and the same method on traversable collections: When called on an iterator, `foreach` will leave the iterator at its end when it is done. So calling `next` again on the same iterator will fail with a `NoSuchElementException`. By contrast, when called on a collection, `foreach` leaves the number of elements in the collection unchanged (unless the passed function adds to remove elements, but this is discouraged, because it may lead to surprising results).

 There are two parts of the old libraries which have been replaced wholesale, and for which deprecation warnings were not feasible.
 
-1. The previous `scala.collection.jcl` package is gone. This package tried to mimic some Java collection library design in Scala, but in doing so broke many symmetries. Most people who wanted Java collections bypassed `jcl` and used `java.util` directly. Scala 2.8 offers automatic conversion mechanisms between both collection libraries in the [JavaConversions]({{ site.baseurl }}/overviews/collections/conversions-between-java-and-scala-collections.html) object which replaces the `jcl` package.

 2. Projections have been generalized and cleaned up and are now available as views. It seems that projections were used rarely, so not much code should be affected by this change.
 
 So, if your code uses either `jcl` or projections there might be some minor rewriting to do.

 * **Conversions** `toArray`, `toList`, `toIterable`, `toSeq`, `toIndexedSeq`, `toStream`, `toSet`, `toMap`, which turn a `Traversable` collection into something more specific. All these conversions return their receiver argument unchanged if the run-time type of the collection already matches the demanded collection type. For instance, applying `toList` to a list will yield the list itself.
 * **Copying operations** `copyToBuffer` and `copyToArray`. As their names imply, these copy collection elements to a buffer or array, respectively.
 * **Size info** operations `isEmpty`, `nonEmpty`, `size`, and `hasDefiniteSize`: Traversable collections can be finite or infinite. An example of an infinite traversable collection is the stream of natural numbers `Stream.from(0)`. The method `hasDefiniteSize` indicates whether a collection is possibly infinite. If `hasDefiniteSize` returns true, the collection is certainly finite. If it returns false, the collection has not been fully elaborated yet, so it might be infinite or finite.
-* **Element retrieval** operations `head`, `last`, `headOption`, `lastOption`, and `find`. These select the first or last element of a collection, or else the first element matching a condition. Note, however, that not all collections have a well-defined meaning of what "first" and "last" means. For instance, a hash set might store elements according to their hash keys, which might change from run to run. In that case, the "first" element of a hash set could also be different for every run of a program. A collection is _ordered_ if it always yields its elements in the same order. Most collections are ordered, but some (_e.g._ hash sets) are not-- dropping the ordering gives a little of extra efficiency. Ordering is often essential to give reproducible tests and to help in debugging. That's why Scala collections give ordered alternatives for all collection types. For instance, the ordered alternative for `HashSet` is `LinkedHashSet`.
