Same question with cull: 2011/8/30 Niko Schwarz <niko.schwarz@googlemail.com>:
It's a question of consistency. Why support value:, but not value:value:?

I proposed this some one or two years ago. I got shut down, but I still find it a good idea.
And I even have a semantic reason: - A Block represents a piece of functionality that can be evaluated with some input - A Symbol often represents a selector which in turns represents a piece of functionality that can be evaluated with some input.
I seem to recall there was discussion some time ago about splitting Selector functionality from Symbol. After all, there's no real reason that a selector has to be a Symbol.
Selector is just a role to identify a method in method's dictionary. It can be any object: if you look how VM does a lookup there's nothing which limits a selectors to be the instances of Symbol (perhaps the only thing is printing a stack trace ;).
What i mean that any object may be a selector:
MyClass methodDict at: 1 put: someMethod.
MyClass new perform: 1
should work.
So, i don't see what you can gain by splitting functionality of Selector from Symbol. Then you should put all selector-related protocol to Object class. And this even worse idea :)
Also, some of the examples in this thread seem to be about terseness for terseness sake.
Yeah. I have same impression. But its cool :)
