I'm very glad to hear it's working for you. The easiest bug to repro
is mentioned on the PowerPatches page on the wiki:
Todo: There are still some bugs surrounding error handling. For
example, from an interactive lua session, if you

IIRC, I think what's going on here is that the yield() in program.lua
is supposed to issue a warning and keep executing, because it can't
