It was just a guess to be perfectly honest. I'll try to benchmark it
tomorrow. If it inlines the function to Fprogn then there is no benefit to
performance (assuming it elides the Lisp_Object completely). The code,
however, is cleaner now. I'll look through the rest of the code for Fprogn
usages.
Sincerely,
Chris Gregory
