=head1 NAME

Data::Perl::Collection::Array::MooseLike - Collection::Array subclass that simulates Moose's native traits.

=head1 VERSION

version 0.001008

=head1 SYNOPSIS

  use Data::Perl::Collection::Array::MooseLike;

  my $array = Data::Perl::Collection::Array::MooseLike->new(qw/a b c d/);

  my $scalar_context = $array->splice(0, 2); # removes and returns b

  my @list_context = $array->splice(0, 2); # returns and removes (b, c)

=head1 DESCRIPTION

This class provides a wrapper and methods for interacting with an array. All
methods are written to emulate/match existing behavior that exists with Moose's
native traits.

=head1 DIFFERENCES IN FUNCTIONALITY

=over 4

=item B<splice($args, ...)>

Just like Perl's builtin splice. In scalar context, this returns the last
element removed, or undef if no elements were removed. In list context, this
returns all the elements removed from the array.

This method requires at least one argument.
