This is logical .. but do we really need another operator?
The syntax is bloating beyond C++ :-)
If some kind of overloading is being considered,
couldn't it apply to record labels too? I guess you'd have to use
a let/type .. and construction:
let f x = x + x
and f x = x +. x
in f 1, f 1.0
type p2 = { x : int; y : int }
and p3 = { x : int; y : int; z : int };;
{ x=1; y = 2 };;
It seems unprincipled that the first case reports an error,
but in the second, the second 'x' hides the first.
