Nested `proc` usage can't use outer owned data

[alexcrichton]

I would expect this code to compile:

fn work(_: ~int) {}
fn foo(_: proc()) {}

fn main() {
  let a = ~1;
  do foo { do foo { work(a) } }
}

Indeed. Seems like a bug.

This has been fixed, flagging as needstest.

Updated example:

fn work(_: ~int) {}
fn foo(_: proc()) {}

fn main() {
  let a = ~1;
  foo(proc() { foo(proc() { work(a) }) })
}
