Sure I get your point. And in many computer languages, '=' is an
assignment operator. I first learned this back in the 60's when I was
using FORTRAN. It has been that way for a long time, and many more
languages use '=' for assignment than not.

But you completely missed my point. This is not mathematics. This is
programming. You don't like the language syntax? You are free to
create your own language.
