The problem is that the latter example is ambiguous - it is the same
as exporting a macro "interface" that implicitly exports the binding
"ARITHMETIC". The former example doesn't also looks confusing to me,
but that is more a matter of taste. The use of a keyword is indeed not
everybodies taste, but I couldn't come up with a better syntax that
is both unambiguous and obvious.
