De-mode vec::each() and many of the str iteration routines 

Note that the method foo.each() is not de-moded, nor the other
vec routines.

Closures in Rust are frequently used in combination with higher-order
functions to simulate control structures like `if` and
`loop`. Consider this function that iterates over a vector of
integers, applying an operator to each:
integers, passing in a pointer to each integer in the vector:
~~~~
fn each(v: ~[int], op: fn(int)) {
fn each(v: ~[int], op: fn(v: &int)) {
let mut n = 0;
while n < v.len() {
op(v[n]);
op(&v[n]);
n += 1;
}
}
~~~~
As a caller, if we use a closure to provide the final operator
argument, we can write it in a way that has a pleasant, block-like
structure.
The reason we pass in a *pointer* to an integer rather than the
integer itself is that this is how the actual `each()` function for
vectors works. Using a pointer means that the function can be used
for vectors of any type, even large records that would be impractical
to copy out of the vector on each iteration. As a caller, if we use a
closure to provide the final operator argument, we can write it in a
way that has a pleasant, block-like structure.
~~~~
# fn each(v: ~[int], op: fn(int)) {}
# fn each(v: ~[int], op: fn(v: &int)) { }

Inside a generic function, the names of the type parameters
(capitalized by convention) stand for opaque types. You can't look
inside them, but you can pass them around.
inside them, but you can pass them around. Note that instances of
generic types are almost always passed by pointer. For example, the
parameter `function()` is supplied with a pointer to a value of type
`T` and not a value of type `T` itself. This ensures that the
function works with the broadest set of types possible, since some
types are expensive or illegal to copy and pass by value.
