NAME

    immutable - Immutable Data Structures for Perl

SYNOPSIS

        my $hash = map(k1 => 123, k2 => 456);
        my $k1 = $hash->{k1};               # 123
        $hash->{k3} = 789;                  # Error
        my $hash2 = $hash->set(k3 => 789);  # Correct

STATUS

    This module is new and too incomplete, buggy and slow to use for any
    real code.

    It is being developed for use in Lingy, a Perl version of Clojure,
    which needs immutable data types.

DESCRIPTION

    The immutable module provides immutable versions of native Perl data
    structures.

    Immutable data makes programs easier to reason about, and is
    foundational for functional programming and concurrency.
