Spoke too soon. I seems all you needed was to change:
full_regexp = "|".join(as_regexps) + "$"
full_regexp = "$|".join(as_regexps) + "$"
However, I noticed rex still doesn't return multiple matches. For
instance, matching 'abc' to the given the patterns '#bc', 'a#c', and
'ab#', your code only returns a match to the first pattern '#bc'. Is
this standard behavior or is it possible to change this?
