-- haxe-parity Task 1 (modules): `a` and `b` both export a `pub fn
-- thing`. Resolution goes file -> own module -> used modules -> stdlib
-- (this file's own module has no `thing` at all), and at the "used
-- modules" tier both `a` and `b` match — collisions diagnose rather
-- than shadow silently (WO-E218), never a first-used-wins pick.
use a
use b

fn main() {
  print_int(thing())
