Hi,
Looking at the Rust documentation, I read:
----
Named functions, like those we've seen so far, may not refer to local
variables decalared outside the function - they do not "close over their
environment". For example you couldn't write the following:
let foo = 10;
fn bar() -> int {
ret foo; // `bar` cannot refer to `foo`
}
Rust also supports closures, functions that can access variables in the
enclosing scope.
----
I can't help but asking why can't named function close over their
environment?
In the case above, I see no harm in allowing the 'bar' function to
access 'foo'.
David
