[parenscript-devel] Loop return values don't get returned

[Vladimir Sedach]

That's completely correct. I probably forgot that I didn't finish the
functionality before pushing out a patch. I've pushed a fix that
returns the value, but warns about "returning from unknown block."
That will be fixed later - the loop return code is kind of weird right
now.
