jerrygarciuh has asked for the wisdom of the Perl Monks concerning the following question:
Greetings fellow monks,
On pg 95 of Camel SE there is a discussion of C operators missing from Perl. A comment is made that "Perl's variable prefix characters serve as dereference operators".

What does that mean?
Is that solely in the context of something like:
${$orig_ref} += 100;
Or is a $ always dereferencing in some way I don't get?
TIA
jg
