for each loop don't work in 3.0 and trunk:

What's missing here is a
import vec::each;
however this would be more idiomatically written as
for the_vector.each |n| { ... }
also it is possible to get the value from this loop:
import io::println;
fn main() {
for 5.times {
println("Here's some Rust!");
}
}
The preferred way (at least, my preferred way) is to use `uint::range`
or `int::range`, depending on whether you want unsigned or signed
integers. For example:
for uint::range(0, 5) |i| { ... }
This may change as we revamp our APIs. At minimum, the `uint` prefix
will probably go away and range will be replaced by a generic function
that can iterate over any "integer-like" thing.
