Why isn’t (>>>) a method?

Hi all,

I just want to support Wolfgang here.

These changes (the new Category/Arrow solution) passed me by completely
(too many other things to do).

But I can't really see any strong reason for breaking backwards
compatibility here by not sticking with (>>>) as a method?

In fact, given that Category interferes with the standard
prelude, I wonder if it was considered making (<<<) and (>>>) and
"identity" methods of Category, leaving (.) and "id"
alone?

Such a design would have been beneficial for a library like Yampa,
would have minimized backwards compatibility issues, and would
have simplified life for end users (saves them from hiding the
prelude "id" and (.).

Best,

/Henrik
