Step 1: you ban operator, [comma], either
a) completely (prefered)
b) inside brackets
Step 2: you define , as tuple constructor:
x,y,z -- a triple
(x,y,z) -- if you only banned , inside brackets
where t == (x,y,z)
See Felix. This is exactly what I do. It is also exactly
what SML does.
Note: there is no tuple with one element!
