… is there any way to pass that domain list to, e.g, ${reduce}?
For testing purposes I’d like to do something like:
-----
${reduce {+mydomains}{}{${if eq{$value}{}{}{$value,}}$item}}

… and have it give me “mydomains”, joined with a comma.
${listnamed_d:mydomains} as source for your reduce.
Bear in mind that you a vulnerable to list elements
that already have an embedded comma, and ones with
an embedded colon may surprise you.
It'd be nicer if listnamed had a way of getting a
custom output separator, and/or if reduce did full
list expansion, of course.
