→Perl 6 comment on the need for Y?
Line 60:
:''"The task is to define the stateless Y combinator and use it to compute factorials and Fibonacci numbers from other stateless functions or lambda expressions."''
Unfortunately you haven't defined it, and it seems as if it hasn't been used to compute the two functions. --[[User:Paddy3118|Paddy3118]] 05:54, 5 June 2009 (UTC)
==Perl 6 comment on the need for Y?==
Can anyone explain the comment:
:''"Note that Perl 6 doesn't actually need a Y combinator because you can name anonymous functions from the inside"''
I cannot make sense of it as the Y combinator seems to be a way of adding recursion to mainly theoretical functional languages that don't allow variables holding state. I doubt if any of the RC languages actually ''need'' Y so it seems superfluous. --[[User:Paddy3118|Paddy3118]] 09:51, 11 September 2010 (UTC)
