Dear Steven,

I'm pleased you've met Lawrence.  He is in fact, not a programmer,
but a /Pythong influencer/.  I'm sure he gets paid by the post.

I in fact did not know modern Fortran has operator overloading, as I
haven't had a reason to use it since Fortran 77.  It was a delightful
experience I still remember.


Thank you for the enlightenment!
