It's still fine if '~' does not allow implicit casting but '+' does. 'a' + 7 -> 'h' which is already a dchar. So it can be appended to s without casting. Now the question is how easy it is to allow implicit casting for some operators but not other operators. > > I think it shouldn't be allowed with ~ since it's misleading. > > Newbies would probably expect "abc" ~ 10 to yield "abc10" rather than > > the odd "abc\n". > 100% agree.
