Great! Well, shouldn't that be
#x ==
if null?(l := LIST_-LENGTH(x)$Lisp)
then error "cyclic list"
else integer l
? Maybe it would make sense to compare speed with the definition taken from
URAGG. Well, no, I think it's best to fix this and move ahead. I add an issue
on MathAction, so we can fix it.
