--- Comment #18 from Tom Tromey <tromey at gcc dot gnu.org> --- (In reply to Tom Tromey from comment #17) > It seems that "force" works on function parameters and casts > but not direct assignments: It's also an error in conditional expressions and in a "return". I can implement this exactly but I'm curious whether it is intended.
