Hope I didn't miss anything...

That's the crucial point: You never know. Perl is a language with a very complex syntax (compared to all other programming languages that I know of) that you can basically never be sure if you approach things in this way.

I thought I was quite confident with Perl's syntax, until I found out that you can have whitespaces between the sigil and the variable, and that even works in string interpolation: 

$ perl -wle 'my $x = 3; print "x: $ x"'
x: 3

I certainly didn't expect that.

What I learned from this is to never assume that you know every detail of Perl syntax, so I won't be sure that I've covered all corner cases. Can you be?
