Always talking about read & write i noticed another interesting thing:
use std::io::buffered::BufferedReader;
use std::io::stdin;
fn main()
{
print!("Insert your name: ");
let mut stdin = BufferedReader::new(stdin());
let s1 = stdin.read_line().unwrap_or(~"nothing");
print!("Welcome, {}", s1);
}
when i run this simple code the output "Insert your name" doesn't appear on
the screen... only after typing and entering a string the whole output
jumps out... am i missing some "flush" (ala Fantom) or similar? I am using
Rust 0.9 on W7.
