Re: Wrapping code in a sub causes an error I don't understand.

I don't use Pod::Usage, so take this with a large pinch of salt.

CAVEATS

By default, pod2usage() will use $0 as the path to the pod input file.

And in the case of calling it not as a script but with -e as you have done, then $0 becomes -e so Pod::Usage fails to open that file. The short answer is either don't use Pod::Usage or don't call it like that.

Additionally, pod2usage should exit so all of those && exit clauses would seem to be superfluous.

Thanks. The `&& exit` clauses come from The Dynamic Duo --or-- Holy Getopt::Long, Pod::UsageMan!, which I have found so helpful down the years that I tamper with the model as little as I can. Perhaps that is cargo cult, but the cargo arrives. :-) Regards, John Davies	[reply] [d/l]

Thanks for the reference. There was already a reply in that thread discussing the unnecessary use of `&& exit` and I've added my tuppence here. 🦛	[reply] [d/l]
