sub fa { my $time = time; my $ref = from_json(@_); $time = time-$time; print "T$time ", Dumper( $ref ),"\n"; } fa(q{["double extra comma",,]}); ## THE BUGGY fa(q{[1,[2,[3],[]]]}); ## THE REGULAR fa( q{[{"k":"v"},{"v":"k"}] } ); fa( q{{"ro":["sham","bo"],"t":{"i":{"c":{"t":{"o":"c"}}}}}} ); __END__ T5 $VAR1 = 'no match'; T0 $VAR1 = [ 1, [ 2, [ 3 ], [] ] ]; T0 $VAR1 = [ { 'k' => 'v' }, { 'v' => 'k' } ]; T0 $VAR1 = { 'ro' => [ 'sham', 'bo' ], 't' => { 'i' => { 'c' => { 't' => { 'o' => 'c' } } } } };
