in reply to Fastest data structure compare?

As repellent noted, JSON::XS is *very* fast. For some data sizes (in some benchmarks) it beats Storable. Here's a sample. Note the examples show the main caveat, JSON cares whether things are numbers or strings.

use JSON::XS; my %bingo = ( one => 1, two => 2, three => 5, ); my %bongo = ( three => 5, two => 2, one => 1, ); my %bango = ( one => "1", two => "2", three => "5", ); print "Is bingo bongo? ", encode_json(\%bingo) eq encode_json(\%bongo) ? "yes!\n" : "noes :( +\n"; print "Is bango bongo? ", encode_json(\%bango) eq encode_json(\%bongo) ? "yes!\n" : "noes :( +\n";
Is bingo bongo? yes! Is bango bongo? noes :(
