Re^2: data structure advice please

you could shorten

$saved_info = $fileinfo{$_} ||= [];
push @$saved_info,\@filedata;
[download]

push @{ $fileinfo{$_} }, \@filedata;
[download]

beacause the arrayref will be autovivified if it didn't already exist.

True. I thought it may have complained that 'undef' (the initial value of $fileinfo{$_}) was not an array ref, but after testing it, I see it doesn't.	[reply]
