I get

No entries on stack!
hihihihihihihihihihi

last changelog entry in my built parrot is on 2002-03-19 22:54 .. so I
guess it's a bit outdated :-)

Actually, that's right. The hi's are correct. The "No entries!" error is because there's a "ret" at the end, and presumably this little segment wasn't called with a "bsr".

I took out the ret (don't forget to add an end!) and it ran fine, even without the commas.
