--- Comment #5 from [email protected] --- Actually, it looks like it's probably the *wrong* fix, because if appender is used with a type with overloaded assignment operator, and the assign operator was un-@safe, then this patch will cause unsafe code to be called from @trusted code, so it will break @safety in a subtle but fairly horrible way. --
