I think we should make all these functions inline - when we introduce
decimal indexing they will be used pretty often.

Hmm, other mp_ methods use assertions instead. Shouldn't we?
Anyway, come to think of it, without seeing how these functions are
actually used, I can't say whether the API is good or bad. Let's
postpone this patch until we introduce decimal field comparators.

When you submit the patch next time, please rework the test so that you
don't have to delete half of the result file. Design it in such a way
that you only add new lines.
