One interesting area is timestamp / datetime related code. There's been some
past efforts in the area, mostly in 5bc450629b3. See the RETURN_ERROR macro in
formatting.c.

This is not directly about type input functions, but it looks to me that the
functionality in the patchset should work.

I certainly have the hope that it'll make the code look a bit less ugly...


It looks like a fair bit of work to convert this code, so I don't think we
should tie converting formatting.c to the patchset. But it might be a good
idea for Tom to skim the code to see whether there's any things impacting the
design.
