Those parentheticals can be rewritten with commas, which sent me on an exploratory tangent trying to see if one could use commas instead of parens in Lisp.
Like a sibling commenter said, commas are not enough to be unambiguous. Ambiguity is fine in prose, because we can resolve it from context, but computers need something clear and well structured.
Me too - I try to avoid parentheticals in polished writing because they're usually there to avoid having to decide if something is really important. If it's not important, take it out (or if it's a very technical detail that can be skipped on first reading, maybe put it in a footnote (uhoh, I'm doing it)).
