metaclass in python, role in perl and AOP in ruby

Lionel Thiry

Hello!

I had some kind of vision the other day:

* Python
It has metaclasses programming since version 2.3.

* Perl6
It will focus on roles.

* Ruby2
If ruby2 focus too much on metaclasses, it would mimic python2.3. If
ruby2 focus on roles, it would mimic perl6. If ruby2 focus on AOP, ruby
wouldn't mimic anything.

it would mimic AspectJ. Or, if we just install the supposed :pre :post
:wrap hooks it would mimic Common Lisp, I think.

How about we don't worry about Ruby mimicing anything? Just let it do
what it does. There's no reason to artificially impose a focus for
Ruby 2 just to avoid "mimicing" other languages. Some would say Ruby
mimics perl right now ($_, $1, etc.), but that doesn't really matter
because it has its merits and its disadvantages just like any other
language. I hope ruby doesn't become an AOP language or a metaclass
language or a role language, but rather a Ruby language.

I sort of figured most modern languages get where they are because
people continually look at other languages and steal the better ideas.

Seems goofy to worry at this point that someone will accuse Ruby of
being derivative or of having features found in other languages.

Everything mimics Common Lisp, but most things do it worse. :-)
