Typeglobs will go away in Perl6, but they will be replaced by a more consistent := aliasing operator. In Perl5 you would write *foo = \@bar in Perl6 you would write @foo := @bar.

Though if I read Apocalypse 6 correctly then

sub foo (@foo is rw) { ... }
foo(@bar);

I don't see a reason to avoid typeglobs if you must alias something in Perl5. Ponie (Perl5 running on Parrot) will certainly support typeglobs, and I don't a good reason to compleatly throw away a useful (but seldom to be used) technique just because the next major version of Perl will not use that syntax for aliases. Should I stop using objects in Perl5 because Perl6 has a totally different object syntax?

Don't get me wrong - I completely agree that you can't throw something away just because it won't be in perl 6 (since pretty much the whole perl5 language would be thrown away). However, I think that tphyahoo's comment was more based on the "seldom used" part of your comment: there are some "more advanced" areas of perl 5 which, if you aren't already comfortable with them, may not be worth the effort to learn at this point. I'm not sure that typeglobs are in that category, but, as a generality, I think the logic makes sense. Where that line is drawn may be different for each person, but that the line exists for some people I think is a reasonable statement.

Personally, I'm a complete geek, and won't stop abusing the crap out of perl 5 until perl 6 is somewhat established. But I can understand how that may not be true (or even should not be true) for some people.
