No, state works just fine with arrays and hashes.
#!/ActivePerl/bin/perl use strict; use warnings; use feature (qw/state say/); store_and_print_hash('a'); store_and_print_hash('b'); store_and_print_hash('c'); store_and_print_array('x'); store_and_print_array('y'); store_and_print_array('z'); sub store_and_print_hash { state %hash; my $key = shift; $hash{$key} = 1; say "Hash keys: (" , join(', ' , sort keys %hash), ")"; } sub store_and_print_array { state @array; my $value = shift; push @array, $value; say "Array values: (" , join(', ' , @array), ")"; }
results in
Hash keys: (a) Hash keys: (a, b) Hash keys: (a, b, c) Array values: (x) Array values: (x, y) Array values: (x, y, z)
