...Or just rename enum

[Bill Baxter]

Another possibility occured to me.
Get rid of the keyword enum and replace it with something that would 
better describe the full scope of the new proposed usages.

For a time, we add a new keyword.  But slowly phase out enum.  Maybe 
issue deprecation warnings after 6 months, then make it a deprecation 
error after a year.  Something like that.

So what to call the new "enum" replacer?

"constant"?

And maybe the actual automatically numbered meaning of enum would have a 
slightly different syntax.  Something to say "hey enumerate these".  I 
think that can be done without another keyword.  If no other means then 
by a paren option like "constant(enum)".

Thoughts?

Really I have no problem merging the /concepts/ of enum and manifest 
constants.  That really does make sense.  The problem is just the actual 
keyword involved here.
