I suggested this in another thread but perhaps it is more pertinent here. I would suggest making use of the '≡' html entity which gives us ≡≡ for 'is' and !≡ for isnot/isnt/!==. I suspect D 2.0 will struggle with all the english based keywords in the future since Unicode support really suggests supporting multiple languages.

"isnt" and "aint" are informal, the others use funny characters...
(quotes, spaces, and exclamation marks are not allowed in keywords)
"not is" does not make much sense? Not more than "is not", anyway.
One possibility is "~is", though. (using same rationale as "~this")

Posted in reply to Anders F Björklund | isnot gets my vote As for MS, well, what can one possibly say to the idea of patenting a keyword? This world stinks, and it's getting smellier by the day.

What about just plain "not" ?

"not" would be more reasonable as a transcript of '!',
but not really logical as a replacement for '!==' ?
Not that it matters, since there probably won't be *any*
replacement for TOKnotidentity whatsoever once !== is gone.
