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/XXX Hello?/);
 # XXX sigh, expecting 'Modification of a read-only value attempted', but
 # Test::More never fails here ???

# Although this really consumes the original array, which is now
# immutable, too:
like( (eval { $a->[0]++; 1 } || $@), qr/WHATXXX/);

is $a->sum, 14;

DESCRIPTION
