in thread typeglob/symbolic reference question

dereferencing is literally accessing something at the address pointed by variable value

Not in any version of Perl. C pointers may be a fact of the implementation of Perl 5, but there is no language requirement for anything of the sort.

    I don't understand your disagreement. The quoted statement seems obvious to me. If your language can dereference, you have references, and if you have references, you have some form of addressing. Dereferencing is the act of finding what's referenced (pointed to) by that reference (address).

      I suppose the use of the word "addressing" sounds awfully much like raw pointers in C to me. I see what you mean; perhaps I'm drawing too fine a distinction.
