Dereferencing a hash? I don't see it in perlref, but it is in perlreftut.If you're talking about examples of dereferencing hash references, perlref does show a lot of them. To name a few (comments are mine)...,
....you can replace the identifier with a simple scalar variable....So does perlreftut, I suppose. Talking about words, that doc doesn't even have a single word of "dereference" or "dereferencing", though it doesn't matter to me. But I didn't know if perlreftut talked about dereferencing a hash, or any other docs. :-)....you can replace the identifier with a BLOCK returning a reference....... $$arrayref[0] = "January"; $$hashref{"KEY"} = "VALUE"; # deref the hash, assign a key &$coderef(1,2,3); ....... As a form of syntactic sugar....... ${$arrayref}[0] = "January"; ${$hashref}{"KEY"} = "VALUE"; # same as above, differet syntax &{$coderef}(1,2,3); ...$arrayref->[0] = "January"; $hashref->{"KEY"} = "VALUE"; # still the same, witha arrow operator $coderef->(1,2,3);
