Hello, looking into Perl 6 syntax I noticed that there are meta- and hyperoperators to perform among others the classical functional map and fold operations. However, if I understood this correctly, you can only use these constructs to lift scalar *operators* to the domain of arrays.
Coming from a functional programming background (I write a lot of Scheme code), I am very much accustomed to use map and fold operations, but experience teaches me that a lot the the expressive power offered by these operations comes not from the ability to pass a predefined operator to them but rather from the fact that one can also easily pass a custom operation. Therefore I think that it would be a nice addition for Perl 6 if the X...X, <<...>> and similar operators could be applied to anonymous subroutines in addition to other operators. If such a syntactic change wasn't possible it would probably be worthwhile to offer methods like map and fold on array instances that take subroutine references as an alternative. cu, Thomas -- When C++ is your hammer, every problem looks like your thumb.
