$\begingroup$ Yeah, the show expression is how I figured out these functions. I can see the use for invisible space (lets you place superscripts/subscripts without needing anything visible to latch on to), and invisible comma (lets you use indexing like in math). It's the invisible apply that has me wondering... $\endgroup$

$\begingroup$ Invisible apply would give rise to things like operator notation (where Ax means "apply operator A to vector x") and combinator formalism (where KS means "apply combinator K to combinator S"). $\endgroup$
