in reply to References quick reference

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 :-)
