Hi,
Does Rust macro have flow control based on a variable value?
I didn't find such info here http://doc.rust-lang.org/guide-macros.html.
I'd like to get a macro expading a for loop.
doTimes(3, println!())
=
println!()
println!()
println!()

Hello all. I just subscribed to this list only because I found something
odd on the Rust Guide, and couldn't find a better place to send feedback.
It's about section 13 Standard Input. The first example code is the
following:
use std::io;
fn main() {
println!(Type something!);
Yup, that leading std:: in main shouldn't be there.

Hi Pablo,
You can submit a pull request at the Rust Github repo (
https://github.com/rust-lang/rust). The relevant file is at `/src/doc/
guide.md`: https://github.com/rust-lang/rust/blob/master/src/doc/guide.md.

The problem is that you're trying to use a trait as a type. This code works
for me
```
use std::rand::{Rng, task_rng};
fn main() {
let rng = mut task_rng();
print_numbers(rng);
}
fn print_numbersT:Rng(r: mut T) {
for _ in range(0u, 10) {
println!({}, r.gen::uint());
}
}

That shouldn't be a problem. You can use a `mut Trait`, and you'll get
dynamic dispatch.
