NAME

FP::MutableArray

SYNOPSIS

            

              
              
use FP::MutableArray;
use FP::Div 'inc';
my $a = mutablearray(1,4,5)->map(\&inc);
is $a->sum, 13;
$a->[0]++;
is $a->sum, 14;
# They can be turned into immutable ones:
my $b = $a->pure;
like( (eval { $b->[0]++; 1 } || $@),
      qr/^Modification of a read-only value attempted/);
# Although this really consumes the original array, which is now
# immutable, too:
like( (eval { $a->[0]++; 1 } || $@),
      qr/^Modification of a read-only value attempted/);
is $a->sum, 14;
is( FP::_::MutableArray->null == FP::_::MutableArray->null, '' );
