[issue1506122] Add "compose" function to the functools

[Raymond Hettinger]

Raymond Hettinger <rhettinger at users.sourceforge.net> added the comment:

I agree with Amaury that this should be closed.  It has been previously discussed and rejected in other forums.  One the issues is that the usual mathematical order is unintuitive and not self-documenting  -- i.e. is compose(f,g)  the same as f(g(x)) or g(f(x))?  Also, it is already dirt simple to create your own compose function or to do the composition directly:  h = lambda x: f(g(x)).
