zeltus has asked for the
wisdom of the Perl Monks concerning the following question:
Looking thru' some legacy code I have to support, I have come across entries like...
I am unclear what the 'do' is for
I have a vague memory of tutorials involving inside-out programming, blessing of scalars and such-like which I think have a bearing on this, but my memory is shot and I can't remember anything else.
Can a Monk put me out of my misery and explain why this was used and why it should (or shouldn't) be used today?
