I don’t see any “active" problems with our current names.  If this is a matter of aesthetics, or an attempt to align with Ruby/Python/Go instead of C/Java etc, then this seems like the wrong direction for Swift.

These are functionally different cases.  We are *omitting* a C feature by removing ++ and --.  This proposal included keeping the name “Double” but giving it a different meaning.

There are good and bad parts of C syntax.  The goal is not to cargo cult all of the bad parts of C into Swift, it is to keep the good parts and discard the bad parts.  For things that could go either way, we should keep alignment with C.
