Missing method: sort

[matepaiva]

Just a suggestion for a method that could be implemented with this lib, once it would be useful to me: sort.

If you like the suggestion, I could work on it (with your help, of course).

Yeah of course. In c# linq it's called orderBy.

A sort function is a good feature, however a purely lazy sort would defeat the purpose of being lazy, since a sort requires at least one cycle through all elements, materializing them. If they aren't cached, the performance can be much much worse than eager algorithms. However an inferred sort would be an interesting feature, having the sort only be executed when the iterator is materialized.
