I think that's the point. For instance, table.sort's default
comparator function only cares that the values you are sorting support
the < operator (and are of the same type). You don't need one function
for strings, another for numbers, another for tables, etc. It would
make sense, in terms of consistency, that any instance where a
function is accepted that a callable object is valid.
