Actually, it shouldn't be too hard to handle the interpolations.  In
fact the language to be parsed is probably mostly pretty simple, and
can be automatically translated to BNF or whatever input your favorite
parsing library wants from the .pot file.  The generated grammar
probably would be on the order of the size of the .pot file, no?  It
could be stored with the .mos as a "pseudo-translation".
