I'm not sure how a discussion about parenthesis ( ) morphed into too many brackets ("curvy brackets" - { }), but I don't see the problem in any case. The use of brackets for block delimiters is visually quite distinct from any other use I'm familiar with so I don't see the problem.
There is a usage of ;; that I don't quite grok, but seems to be fairly common so the ;; option probably wouldn't fly in any case.
Perl's && and and operators have substantially different precedence. They must not be used as interchangeable. Yes, subtle I know, but very useful.
