Maybe it's my math background but I honestly prefer symbols to keywords. It's more up front cost in learning, but it's much more efficient in the long run.
When you are doing multiple operations to multiple variables, and need to see it all at once, math-like syntax still has benefits.
But this is not the common case for most programming, which is about detailing business rules. Explicit and verbose (though not excessively) has been shown to be the most readable/maintainable. For example, one character variable names, common in math, are heavily discouraged in professional development.
There’s another level to this as well. To me, calculus notation looks quite elegant, while Perl and (parts of) Rust look like trash. Since they are somewhat similar, the remaining angle is good taste.
