Why isn’t (>>>) a method?

[Wolfgang Jeltsch]

Hello,

I wonder why (>>>) is an ordinary function instead of a method with a default 
implementation based on (.).  The latter would make life easier in two ways.  
First, it would be easier to write code which works with the old Arrow class 
and the new Category/Arrow solution (fewer CPP stuff).  Second, I often find 
it easier to “think forwards” and use (>>>) instead of “thinking backwards” 
and using (.).  So it would be nicer for me to use (>>>) in a method 
implementation instead of (.).

Best wishes,
Wolfgang
