Ah, but suddenly a function which has only returned one value returns two .. here again I'm reminded of the special care one must take with string.gsub.  Better it be a different function, then.

 

print(type(1, 'subtype'))
number    integer

???

Or the possibly buggy approach of:

types(1)

number, integer

I think subtype is very nice, but I overload type to work with hierarchies of types (more than two). Subtype could be used in the same way, but it struck me as singular, like type is.
