This argument ignores the fact that Lua does indeed treat integers
specially.  This even goes beyond implementation details.  One
user-visible way is that the semantics of operator # are defined based
on integers.

So we've got operator # that relies on integers, operator % with is
particularly well suited to dealing with integers.  Certainly it's a
reasonable assertion that integers have a role to play in Lua, and I
propose it's not wildly out-of-line to request an operator that is the
natural compliment to %.
