Reverse the order of what? ArcTan of one argument has only one argument and
how can that be reversed? What has two arguments is the coordinate
specification {x, y} and they are not reversed in ArcTan[x, y].

It is the one argument form ArcTan[y/x] that seems poorly designed and would
probably only be used when one knows the quotient and not x and y - so there
wouldn't be anything to reverse.

(simple example: why does Mathematica reverse the order of arguments to
arctan of 2 args?)
