Dereferencing a hash? I don't see it in perlref, but it is in perlreftut.

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....

...
$$arrayref[0] = "January";
$$hashref{"KEY"} = "VALUE"; # deref the hash, assign a key
&$coderef(1,2,3);
...

....you can replace the identifier with a BLOCK returning a reference....

...
${$arrayref}[0] = "January";
${$hashref}{"KEY"} = "VALUE"; # same as above, differet syntax
&{$coderef}(1,2,3);
...
[download]

.... As a form of syntactic sugar....

$arrayref->[0] = "January";
$hashref->{"KEY"} = "VALUE"; # still the same, witha arrow operator
$coderef->(1,2,3);
[download]

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. :-)

Lots of examples of something a little different. None of those example return the referenced structure, which is what the OP wanted.
