+Unlike closures, procedures may only be invoked once, but own their
+environment, and are allowed to move out of their environment. Procedures are
+allocated on the heap (unlike closures). An example of creating and calling a
+procedure:
+
+```rust
+let string = ~"Hello";
+
+// Creates a new procedure, passing it to the `spawn` function.
+spawn(proc() {
+  println!("{} world!", string);
+});
+
+// the variable `string` has been moved into the previous procedure, so it is
+// no longer usable.
+
+
+// Create an invoke a procedure. Note that the procedure is *moved* when
+// invoked, so it cannot be invoked again.

 ### Object types
 
 Every trait item (see [traits](#traits)) defines a type with the same name as the trait.
