I'm betting it wouldn't help. I was considering something along the line
of unrolling the loop:
Assert(list_length(object) == 2);
assign typenames[0] and typeoids[0] from linitial(object)
assign typenames[1] and typeoids[1] from lsecond(object)
This would involve duplicating the loop body, but that's only 3 lines,
so I think it wouldn't even net out as more code.
