This probably a perl question so if I should ask elsewhere let me know...
In looking at the Mojo::Pg blog example and in recent addition of db
method to Mojo::Pg::PubSub I see use of shift->.
From Mojo::Pg::PubSub documentation:
# Reconnect immediately
$pubsub->unsubscribe('disconnect')->on(disconnect => sub { shift->db });
Or from the blog example:
$self->helper(pg => sub { state $pg = Mojo::Pg->new(shift->config('pg')) });
This doesn't work in my code and I replace "shift" with "$self". That
appears to be working. Also, I can't reconcile using shift in this way
and what the perl documentation says about it but could get over this if
it worked.
What am I missing here?
Thanks,
John
