Mo::build - Adds the build feature to Mo

Synopsis

    use Mo qw'build';
    has name => ( is => 'rw' );

    sub BUILD {
        my $self = shift;
        ...
    }

Description

Adds the BUILD feature to Mo when imported.

If a sub called BUILD exists on the package, it will be executed on $self during instantiation.

Any non-lazy default and builder attributes, as well as any value passed to new will already be set when BUILD is called.

    package ABCD;
    use Mo qw'build builder default';
    use feature 'say';

    has a => (default => 1234, lazy => 0);
    has b => (builder => '_b', lazy => 0);
    has c => (is => 'rw');
    has d => (is => 'rw');

    sub _b { 'blue' }

    sub BUILD {
        my ($self) = @_;
        say $self->{a};
        say $self->{b};
        say $self->{c};
        say 'undef' unless defined $self->{d};
    }

    ABCD->new(c => 'days') # => 1234
                           #    blue
                           #    days
                           #    undef
