each_char conflict in str::StrSlice and io::ReaderUtil

[sbillig]

This code fails to compile:

use core::str::*;
fn main() {
    let s = ~"hello";
    // Works:
    each_char(s, |_| {true});
    // Fails:
    s.each_char(|_| {true});
    // Fails:
    for s.each_char |_| {}
}

error: failed to find an implementation of trait core::io::Reader for <V2>

I ran into this too - I think it might be the same bug as #4270.

Ok, so, each_char the function no longer seems to exist, and the each_char method for StrSlice no longer exists. The test still fails, since there is no Reader implementation, but that seems right.

So I'm closing this.
