The following code snippet does not emit any compilation warnings about
redeclaring variable names or types:
fn x(y: int) -> ~str {
let y = y + 1;
let x = y == 2;
let x = x.to_str();
x
}
Is this a feature or a bug? The Rust manual has no comment. This behavior was
surprising, but I actually it. I use a similar pattern in Python when
transforming a variable to a different type. I don't want to make up a new (and
uglier) name when I no longer care about referencing the old value.
