I cannot believe that you've never seen anyone being confused by this.
You have been around in Perl world much longer than I have, and I have
seen it numerous times.

Indeed. I already said that.

I'm certain that you can estimate my Perl competence very well. Indeed I
have much to learn.

Very true. However, it causes inconsistency between parens and
everything else.
I hate such inconsistency, but you think it's acceptable.
You hate giving up whitespace, but I think it's acceptable.

It's not optional in Perl 5. It's forbidden.
This is just a syntax change.

This is necessary in order to establish progress elsewhere, or so Larry
