Hi Kevin,
This was interesting! I see what the difference is between your example and
"Dumper(\%entry)", but I wish I also understood what the man page says
about this:
<man Data::Dumper>
In the extended usage form, the references to be dumped can be given
user-specified names. If a name begins with a "*", the output will
describe the dereferenced type of the supplied reference for hashes and
arrays, and coderefs.
</man>
The 1st sentence I understand, but not "the dereferenced type of the
supplied reference."
I just tried this without the asterisk and get "$entry" instead of "%entry"
(or "$VAR1" using the plain procedure).
So in plain(er) English that means: if the name begins with an "*", the
output type will match that of the referenced variable"?
