Sure, and then it will be used by you and two others and 98% of the Perl code out there will remain unintrospectible by your pet interface. > What Perl 6 provides is just a default way of doing it.

Sure, and it also doesn’t buy you anything, because your solution won’t be able to cope with most code. > Perl 6 has a lot of nice features.

It’s not as important as other things, but it opens the door to a class of things that are not generically doable in Perl 5, so I’d say it’s pretty big in its own right, even if it’s not the foremost reason to adopt Perl 6. > explicit call semantics are […] nice not because they provide > better introspection for the user, but because they might > increase perl's ability to do compile-time validation, for > example. They are a nice feature for both reasons. This isn’t an either-or matter. That they have additional (and arguably more important) effects than introspection annotation ensures that people will use them even without having introspection in mind, which makes them yet more valuable for introspection. A nice synergy. ---- In any case, I stand by my assertion that introspection in Perl 5 is possible, but fraught with problems. That Perl 6 will fix most of that is just a side note I threw in, and I stand by that too. That this is the biggest reason to adopt Perl 6 is something I never said, and if you had the impression that I did, then it’s because you read into my arguments something that wasn’t there.
