Lvalue attributes support for Moo, the light Perl object system.
First we had the old school perl (the convenient but fragile)
$$self{x} += 2
Then we had the Moo way (robust but boring to read and write)
$self->x( $self->x + 2 )
But still we were frustated because perl6 and
ruby does it better.
Now we have MooX::LvalueAttribute (convenient and robust)
$self->x += 2
Of course it works with all the operators including (re)affectation.
$self->x = 2;
$self->y //= 10;
Learn about :lvalue from the
subroutines section of the perl documentation.
