No, they aren't. You can either have a sequence of punctuation symbols
or an identifier, but not both in the same symbol. (Actually, I could
change the lexical syntax to make that possible, but I don't think that
this would be a good idea.)

That was my idea with '+:'. I can easily read that as "plus i times".
'+!' looks nice to me, too. ('+:' might confuse Haskell programmers as
they'll easily mistype it as ':+'.)

That's not possible. The parens/brackets/braces are reserved delimiters
which cannot occur in an operator symbol.
