Regarding this example:
' ' x
y
I thought the answer should be:
=> (quote ((quote) x y))

I don't think that's true. After all, in I-expressions AND normal
S-expressions,
''x
=> (quote (quote x))
> The above should have read:
'
' x y
I think that should be acceptable, but not REQUIRED. It's annoying to _have_
to give up so much vertical space.
It's also not what the spec says; the spec clearly recurses back to "expr", so
' ' x
should work. Granted, the spec has errors, but I think in this case it should
be acceptable, and the spec accepted as it is.
Regarding group:

Okay, I understand your goal for "group" better now. That makes sense... but
in that case,
what _should_ the spec say?
