Well, first of all, redefinition of "/" was not permitted (or there would be
no point)
But more to the issue, I have said that the problem was the use of default
division operator on an integer number.
Yes, I can write any sorts of custom functions called "/" too. So what?
The question was if or when compiler should catch trivial mistakes
like that and, at least, warn you "Are you sure?"
