Use of 'at' sign and comma

[Tim Johnson]

This is a smbihm (stop me before I hurt myself) kind of question:
I'm writing a function that processes a list recursively. I'm using
@
at the beginning of a sublist to signal the function code to concatenate the rest of
the sublist into [var="value"] pairs
and
,
at the beginning of the sublist to tell the function code to evaluate the remainder
of the sublist.
<grin> sounds like a certain _other_ lisp doesn't it?</grin>
Any potential problems with that "down the road"?
thanks

I wouldn't expect problems with that.

Thanks. I didn't think any symbol would be a problem, but it is good
to have a second opinion.
