Re^3: slicing array based on values but not index

map { push @{$res{$_->[2]}}, $_ } @arr;
[download]

map loops thro' all values of the array @arr - setting $_ to each value (an array ref.) in turn - pushing that value onto an array in a hash keyed on the last element of each individual array.

As you can see, the result you're interested in is the array of values of the newly created hash.

It can also be written as: `push @{ $res{$_->[2]} }, $_ for @arr;` [download] Some people are finicky about `map` in void context.	[reply] [d/l] [select]

TFT ikegami , I keep forgetting the for idiom you suggest - I really should remember to use map when and only when, modifying (elements of) the input list... A user level that continues to overstate my experience :-))	[reply]
