If I understand what you mean, these already exist in the form of the
built in functions(like "R", "TH", "PH", and whatever you can make with
the trig functions like atan()). And you can construct your own
functions to do whatever you want, just declare them.
#declare WeirdCoordinateA = function {blahblah}
#declare WeirdCoordinateB = function {blahblah}
#declare WeirdCoordinateC = function {blahblah}
Then just use these functions as returning the coordinate values for
your function.
