this is about adding "isBlank" or "isPresent" which don't exist.
My point was that you only need one of them, not both. I don't see
what's the advantage of adding both isBlank and isPresent, when adding
just one will already give you the functionality of the other. I didn't
mean to say that it's a bad idea to add *either* one.
Then why not remove the binary "-" from D. You can always do:
a + -b
I believe this makes the language simpler.
