Yes, a lot.

I use a plug in for vscode that does all sort of substitutions along with ligature.

E.g.

    (reduce + [1 2 3])

Shows as

    (Σ + 123)

Or

    (comp foo bar quax)

Becomes

    (∘ foo bar quax)

Etc, I find the conciseness so much easier to read.

Unfortunately the plugin can be buggy when you hsbe a lot if subs, I'd setup loads if I could. If only someone would fix it / make a version that works.
