That looks really useful.  IMO there is room for both functions (seq
and multi_lookup). In the first instance multi_lookup could be
implemented in C but at a later date if your much more powerful seq
stuff gets added then that may enable multi_lookup to be implemented
in terms of seq.

I'm happy to have a stab at putting together a patch for multi_lookup
if there is any interest?  I'm keen to know if people like the idea,
don't like the idea or are indifferent to it :)
