I prefer the core parenscript to be exactly equal to javascript with
sexp syntax. I suggest another layer/language/something for Lisp-like
additions like this. We have had a discussion about this before, one
of my main points is that It makes it more easy to know what
javascript is generated from your parenscript code.

The easiest thing is perhaps to add a prefix (for example the letter
L) or postfix(for exampe a +) to forms that do magic stuff.  So
lambda+ and defun+ could have return values like this. I think the
recent addition of optional and keyword parameteters (which by the way
is a nice feature) should also go into a lambda+ function instead of
the core parenscript.

Best wishes,
