Predicates are actually _more_ clean, and yet aren't incompatible
("isnumber" and "isinteger"/"isfloat" can exist simultaneously).

If you are worried about function namespace pollution (I'm not,
particularly, but ...), it's also possible to use a predicate-style
solution with a separate type namespace, e.g. "istype(OBJ, TYPE)",
where TYPE is 'number', 'float', 'table', etc.
