Hi.

Excuse me for my poor english.

I need, for recursive requirements, call a block inside the same block. That's possible on Smalltalk?

Integer>>benchFib

...

For example:

"fibonacci function" [:fnc :n1 :n2 :limit :numbers | numbers add: n1. (n2 < limit) ifTrue: [ fnc valueWithArguments: {fnc . n2 . (n1 + n2) . limit . numbers}. numbers ]].

The objetive is use that block without the :fnc parameter.

[:param | param >0 ifTrue: [ thisContext closure value: param - 1 ] ] value: 5 but this will be much slower than just use recursion with methods because of thiscontext.
