Re: Coding superstitions

Ok George,

I confess I always wrap array references: @{$arr}
I also use many unnecessary parens: my ($onevar);
Subroutines that return values always: return $value;
And I avoid using $_.

Thanks for providing the opportunity to confess my transgressions, interesting subject, but I am still unable to commit to changing my superstitious ways.

I am curious why you would never use whitespace in a hash key. Quoting hash keys for consistency seems reasonable to me. Maybe the real, underlying, superstition is whitspace in hash keys?

Those parens around $onevar with your my create list context, which may or may not be what you want.
