Re: Implicit Times

Thanks, but the issue is not defining the operator.
The issue is Mathematica's implicit assumption of a Times (*) when there's a
space between variables.
The NonCommutativeMultiply (**) already exists.
So when I input
x y//FullForm
I want Mathematica to return
NonCommutativeMultiply[x,y]
instead of
Times[x,y]
Of course I want the explicit Times (*) to
still work the same as before,
x*y//FullForm
yielding
Times[x,y]

Read this Mathematica reference on "operators without built-in meanings".
I assume you could define, e.g., 'CircleTimes' to return whatever function
(including non-commutative multiply) you wish.
