[J3] Syntax for enumeration

Guys, we already *have* an ENUMERATOR statement.


This suggested syntax is IMNSHO completely unacceptable. Having a statement that is a simple list of names is crap. And has no place to put anything useful like an accessibility attribute.


The keyword ENUMERATOR signals extremely strongly that these are not components!


In the common case one would write ENUMERATOR precisely once. This is not a burden, let alone a great burden.

I would prefer this form. Simple and to the point. Emphasizes that a TYPE is involved. And it omits the ENUMERATOR keyword - typing this is tedious. The lack of declarations for the enums signals that these are not components.
