Subject: To quote variables or not
Your question is not about quoting variables, which is bad, but about
quoting hash keys. See:
perldoc -q quoting
A script that I'm refactoring has global variables in two different
styles, e.g.:
$main::global->{form}->{'mailprog'}
$main::global->{form}->{mailprog}
The quote marks don't seem to make a difference, so what would be the
advantage of using them? What are they and what do they do? I don't
recall seeing anything like this before.
In your example the quotes do not make a difference. If you are not
sure about why you should need quotes then you should probably always
use them.
