Ignore errors while evaluating with `primitive-eval'

[Alexandru Cojocaru]

Hi guys,
is it possible to ignore errors when evaluating a badly formed expression?

Take as an example this:

    (let ((cs (string->list "display")))
      (let l ((cs (cdr cs)) (s (car cs)))
        (primitive-eval `(begin
                   (,(list->symbol s) "aha")
                   (newline)))
        (if (not (null? cs))
        (l cs s))))

I would like to ignore all the errors while evaluating `(d "aha")', `(di 
"aha")', `(dis "aha")' etc.
and evaluate only `(display "aha")'.

What I want is to construct some (possibly incorrect) expressions on the 
fly and evaluate them.

Best regards,
