How can i cast from int to float?
that is:
let x = 3
let mut f = 3.0
f = f * x
this doesn't work... i have to change from int to float... is this possible?
Use `as`; e.g. `f = f * (x as float)`.

`concat_idents!` is currently broken, and it's my fault. Here's a
discussion of how it might be fixed in the future:

So far, I have had a difficult time finding anything definitive on this
except for some rust test code.
fn main() {
// PART 1: works (from rust test code)
let asdf_fdsa = ~"<.<";
io::println(concat_idents!(asd, f_f, dsa));
io::println(stringify!(use_mention_distinction));

You need to include
"extern mod std;" at the top of your program. This will link in the
