I'll update my examples when your examples of how it's been fixed don't use the same arcane syntax and semantics as the 48 year old Bourne shell. That's the whole point, which you're still missing.

> $ bash -c '[ $((1 + 1)) = 2 ]; echo $?'

Not even Perl uses that much arcane punctuation to test if 1 + 1 = 2. As if [] isn't enough, you've got to throw in two more levels of (()), plus enough grawlix profanity for a Popeye comic strip. And people complain Lisp has too many parens. Sheez.

There's even an emoji for Unix shell syntax:
