on #2, I would prefer:

(5 x) ==> (is 5 x)

...and also:

('foo x) ==> (is 'foo x)

...assuming that doesn't cause a problem I don't see right now...

I don't like this because then you have inconsistent behavior between types. It feels like you're saying, "If you can find something useful to do on function call, do that... otherwise just run is." Why wouldn't

  ((table) (table))
work?

I don't like it. What does (tb x) mean ? Does it mean "look for the key 'x in table 'tb" (provided 'tb is a table) or "is variable 'x holding the same thing as variable 'tb" ?

However, I think this could be a good candidate for ssyntax :

  foo?x ==> (is foo x)

Definitely like that idea. Using is is a real pain and I have to use it all the time.

The problem I see with the second one is:

  ('foo) x) == ((quote foo) x)
so there would be no way of telling if you were trying to do a list-ref.
