That should be a domain error (semiduals make sense only when called
dyadically). Fixed for next beta.

Please fix typos when you find them. It's a wiki.

There were some words in Details 1 of
https://code.jsoftware.com/wiki/Vocabulary/quote ; also buried at the
end of the first paragraph of that page. I have added a bit there to
make it stand out more.
The real question is How would a programmer answer the question, "How do I apply a
different verb to each cell of a noun?" We intended to have a FAQ for such
questions, but I don't know that it ever took off.

Language addition: gerund"r: the left operand of m"v can now be a cyclic gerund, giving a sequence of
verbs to be applied to corresponding cells of the arguments. At long last you can apply a different verb to each
cell of a noun. For compatibility with the older uses of m"n, the gerund is recognized only if the ranks v
are not all infinite and m is a list of boxes containing a valid gerund. This is an incompatible change only if
you used m"n with finite rank and an m that looked like a gerund. In that case, you need to replace m"n
with m"_"n.
