Personally, on Lightroom, I wished for the ability to store nil in
the userdata environment table.
That's harder. Currently it's a pointer to something that can be put
list, which excludes nil, bools, numbers and lightuserdata. Changing
would be a much bigger patch, and would increase size of userdata
Nil doesn't require an expansion of the data structures since a NULL
pointer will do. It does require an expansion in the C code to deal
with that case but possibly not much more than the expansion needed to
handle types other than a table.
