I thought this code would do what you say is impossible (I do believe

What you're doing (in the code you posted) is pretty different from
what I said is not possible (in the message quoted below).  Anyways,
I don't think you'll get far in the path you're taking.  You need a
simpler solution (and a simpler problem): one that you can easily
explain and handle, instead of the trap you're setting for yourself.

It's the same thing. You want to handle the syntax-error exception by
replacing the offending expression with another one of your choice.
The replacement may be just #f or (asserion-violation 'foo "unbound")
or whatever.  Still, not possible to do correctly without hacking on
psyntax.
