Hi Gil,
You said: "...FORTRAN (which lacked relational operators.) ..." Have you
never heard of ".EQ."?

It may have started with FORTRAN (which lacked relational operators.)
In the day I knew some mini computer languages which distinguished
assignments with a token such as:
LET X = A + B
I worked next to a physics graduate student who wrote a FORTRAN
program with a matrix of assignments that visually resembled a
system of linear equations. Somehow, with remarkable persistence,
he got it to compile and print out a vector of variables.
Only *then* he asked me for help: "Why did it not solve my system‽"
