I'm not in favor of adding another list variant code just for that;
the overhead is nonzero, and the gain negligible. (I think the reason
we have OID lists is the idea that someday we'd want to make OID 64-bit.
A list type defined as "UInt" would offer no such future-proofing.)
The code you quote probably ought to be casting the result of lfirst_int
to uint32, but I see no reason to work harder.
