Highlight functions when they are used as functions #3
Description
Some functions (namely eval and transforming functions, off the top of my head) should only be highlighted when we know they are being used as a function. Syntactically, this is when they are used with parentheses.
Instead of greedily highlighting them, we should do something similar to our conditional regex for eval functions.
I released v1.0.0 without this, despite knowing about this bug, as I thought it very minor.
