In Lua, I started to replace (see r23367) :

by
[ 'Lua'; 'io' ]

I take it that :: can still appear in typenames, as in PAST::Op, but
not, for instance like so:

.local int some::var

Is that it?

Yes, that's still fine. In fact, any character that can be represented 
in any character set that Parrot supports is valid in string names.

Yes, it's deprecated in bare identifiers. The '::' was added as a 
special case for Perl identifiers, so we either had to add special cases 
for all the languages, or just declare that if you want a sub, class, 
etc. with interesting characters you need to give it a string name.


The second option makes more sense, as the set of languages that run on 
Parrot is open-ended, and the bare identifiers aren't accessible to 
user-level code anyway.

Also a good change. This gains you the benefits of true hierarchical 
namespaces, and means that different languages that use different 
characters as class name separators can use your classes.

 there are some tests that explicitly use this feature; don't remember which
 ones, but I found some yesterday. I guess these tests can be removed (as
 their sole purpose is to test something that's going to be removed)

 so, shall I remove those tests?

yes, as long as that's what they're testing. that's a normal part of
deprecation.

I *think* so...

As the note says, this is from pdd19. I'd use svn blame to figure out  
who added it there and bounce it off them.


Thanks for investigating.
