This choice, whether to use an existing form e.g., .xyz., or a "random
non-letter character" is best left to the programmers.  This is clearly a
case where it should not up to any one here to inform them what is best for

The standard-bearers for Fortran should ever strive to provide a more
expressive language for Formula Translation, otherwise it does a disservice
to the decades of work on Fortran starting from its very inception and the
investment in it by the practitioners.

Say someone has authored what they think is a performant solution for their
needs toward matrix operations of transpose, Ax = B solution, etc.
Currently the author can define an operator with a "non-letter character"
(/) for matrix right division, but not the left division.

But now "\" is not "random", it is well-accepted for the matrix left

Why is the Fortran practitioner disallowed from defining an operator( \ )?

It does not make sense.
