LISP is a fantastic language where everything is an s-expression and most people's brain's explode at that point. Sugar that makes code faster and easier to read is what most people want. For mathematical expressions having operators makes the code read closer to the math. Somewhere ages ago I did an example of a trivial mathematical expression with and without operators.

When I was a student I had a rant at a prof that showed me his "image processing library" code which used lots and lots operators like:

Insanely stupid right? Except the target audience wasn't production code..it was for students taking class where the reasoning was about math on images.
