 A _local variable_ (or *stack-local* allocation) holds a value directly,
 allocated within the stack's memory. The value is a part of the stack frame.
 
-Local variables are immutable unless declared with `let mut`.  The
-`mut` keyword applies to all local variables declared within that
-declaration (so `let mut (x, y) = ...` declares two mutable variables, `x` and
-`y`).
+Local variables are immutable unless declared otherwise like: `let mut x = ...`.
 
 Function parameters are immutable unless declared with `mut`. The
 `mut` keyword applies only to the following parameter (so `|mut x, y|`
 and `fn f(mut x: ~int, y: ~int)` declare one mutable variable `x` and
 one immutable variable `y`).
 
+Methods that take either `self` or `~self` can optionally place them in a
+mutable slot by prefixing them with `mut` (similar to regular arguments):

+    fn modify(mut ~self) -> ~Self;

 Local variables are not initialized when allocated; the entire frame worth of
 local variables are allocated at once, on frame-entry, in an uninitialized
 state. Subsequent statements within a function may or may not initialize the
