Spoke too soon. I seems all you needed was to change:

full_regexp = "|".join(as_regexps) + "$"

to:

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?
