this will not fix it, but make it worse.
I think a better warning would be
warning: ~ on boolean value, did you mean ! ?
Could you please open a PR? I'll take care of it.
Still not sure about other operations. I guess no one would
object to warning on bool1 % bool2, but should we warn for
bool1 + bool2?
Wouldn't the desire for a warning largely depend on the type of the
result? So I'll assume you're referring to a boolean result :-)
bool1 + bool2 does have meaning though, even when the result is a bool.
You have to be leery of both having a true value as that causes an overflow.
