Hash slice?

John M. Dlugosz has asked for the wisdom of the Perl Monks concerning the following question:

Isn't there a way to get a list of things from a hash? Consider

[ $x{a}, $x{b}, $x{c}, $x{d} ]
[download]

I seem to remember seeing a syntax somewhere that used @x{...} like we use for an array. Am I remembering right?

something like this? `my %hash = ( a => 1, b => 2,c => 3, d =>4); my @list = @hash{'a','b','d'}; print @list;` [download] For more info look at perldata particularly the part about slices -enlil	[reply] [d/l]

`@list = @x{ qw( a b c d ) }` See perldata for details. `perl -le "print unpack'N', pack'B32', '00000000000000000000001011000011'"`	[reply] [d/l]
