I am deep in some legacy code (not written by me) that looks like this (it's surrounded by an if): 
@{ $self->bar || +[] }

[download]

What's with that '+' in there? I mean, I get that it is usually used for disambiguation (e.g. @{ $self->bar || +shift }). But, what makes this plus needed?

(I'm not a Perl beginner, but I have never seen Perl like this: is this a dumb question?)
