Re: p:count

/ Innovimax SARL <innovimax@gmail.com> was heard to say:

You don't have to buffer the stream, just read it. It's true that you
don't get an answer until you have read the whole stream, of course.

We have other steps that produce answers this way, it doesn't seem too
large a burden.

We could, but it would be a lot more difficult to implement that way.
You really *would* have to buffer the whole input stream. As a step,
it's clearly a "heavyweight" operation that destroys (discards) its
input. As a function, I think users would imagine that it's a lot more
lightweight.
