I meant and invalid data ERROR...
cause doing:
>> type? /dog
== refinement!
so IMHO the return value is erronous. one should not have to do:
if (datatype? type? value) [do something]
whenever they do generic language extensions.
type? is such a core function!!!!!! for dialecting.
type? should raise an error if /a/b/c is considered illegal code
or refinement! if its legal. I can see that it would be usefull for code argument parsing
or refinement sets storing ...
