The

issue !is that !is is ! easy to understand, the issue is that it's a 
bad solution to an artificial problem.   Have word based operators, or 
don't.   The reason 'is' was picked is it's used in other languages for 
equivalence.  I don't see !is anywhere.  If we're not going to stick 
with the standard solution why not go to some other symbol for 
equivalence.   Hell, we could just write :

Foo # Bar
Foo @ Bar

Not to mention that i's and !'s should never be next to each other:

!i!i!i!i!i!i!i!i!i!i!i!i!i!i!i!i!i!i!i!i!i!i!i!i!i!i!i!i!i!i!i!i!i!i!i!i!i!i!i!i!i!i!i!i!i!i!i!i
