Well, there is that too.  But I think to really do that well, you may
have to dump the whole standard library and start again from scratch.
Imperative interfaces just don't mix very well with functional ones.

But I confess that I haven't thought deeply about topics like these
anytime in the last few years.  Maybe adding appropriate layers like
"ranges" does make it possible to meaningfully do functional composition
of imperative algorithms.  (Show me the money!)
