Re: References quick reference

[lachoy]

Great summary. Personally, I find the following:

@{$aRefs[0]}   @{$aRefs{key}}   @{getArrayRef()}
%{$hRefs[0]}   %{$hRefs{key}}   %{getHashRef()}

much cleaner and easier to read than:

@array       @$aRef
%hash        %$hRef
$array[0]    $$aref[0]
$hash{KEY}   $$href{KEY}

Maybe it's just me, but I've been using perl for 4+ years and I have never liked stringing the variable characters one after the other (%$). Particularly epxressions like the third and fourth line in the second group above.

I've always thought that using the @{ } %{ } syntax more clearly and consistently evoked what I'm trying to say -- you can use it with variables, method calls/subroutines, etc. I'm interested if other folks feel differently -- it seems to be a matter of taste rather than an opportunity to define yet another One True Way :-)

I definitely avoid $$hRef{key} and $$aRef[0] (using $hRef->{key} instead). But I don't really like @{...} much (too hard to match up the open and close braces) so I prefer @$aRef and %$hRef to the versions with {}. For @{$aRefs{key}} I have no choice.

But when (and if) a version of Perl comes out with "the patch" applied, I'll be switching to nearly exclusively using -> to deference. This patch allows $aRef->@, $hRef->%, $aRef->@[1..5], etc. which are particularly nice for cases like $aRefs->{key}->[0]->getList()->@[2..6].
