It would be great if we had a class for finite sequences with instances Data.List, Data.Array, Data.Sequence. Maybe the new identifiers (<|), (|>) and so on should be names of methods of a such a class instead of separate functions.

I can't think of many useful functions that RP> would use that interface, what with (<|) lazy for lists and strict for the other two, and (|>>) cheap for sequences and expensive for the other two. at least, it will be great to have analogues of length, map, filter, partition and a number of other operations defined in classes and supported for variety of data structures. i think it's omission in H98 standard that this names belongs only to lists and not defined in some classes like (+) and (>) -- Best regards, Bulat mailto:bulatz@HotPOP.com
