As inspired by Prolog:

     x, y :- x + y

So this:

     f = lambda x, y: x ** 2 + y ** 2

Or this:

     def f(x, y): return x ** 2 + y ** 2

Becomes this:

     f = x, y :- x ** 2 + y ** 2

And would logically transpose into this:

     f(x, y) :- x ** 2 + y ** 2

Oooo...this rabbit hole is fun!
