[Jprogramming] What does gerund^:n do?

Sat Nov 17 15:39:05 UTC 2018

No. All I see are domain errors when you try gerund^:n . The question 
is, For what values of gerund and n does gerund^:n not fail, and what 
does it do then?
(I already know the answer because I'm looking at the source code, 
wondering whether this is functionality we ought to keep)
