(just before postfix:<++> on Any/Numeric/Cool is described) Also: <sisar> pmichaud: note that the bug only occurs when $x is uninitialized. The spec is silent(?) on incrementing uninitialized Bool variables. <pmichaud> sisar: I'm expecting uninitialized Bool to work like uninitialized Numeric <pmichaud> principle of least surprise :)
