Yep. The solution to comma issues isn't to put every single one in a place nobody usually puts them - it's to be more forgiving about allowing the occasional trailing one.
Nix made this mistake of using whitespace to separate list elements AND using whitespace to separate a function from its argument and it is a very common pain point for new users, because they will write something like this:
[ theFunction theFunction'sArgument ]
[ (theFunction theFunction'sArgument) ]
