Re^3: Hash assignment "odd" ness

Dumper takes a list of scalars for input. If you want to dump a hash, you need to pass a reference to the hash.

print Dumper(%hash);   # Dumps the result of evaluating the hash. Meh.
print Dumper(\%hash);  # Dumps the ref and the referenced hash. Good.

On the other hand, $po is a scalar. No need to pass a reference to it.

print Dumper(\$po);  # Why??
print Dumper($po);   # Good.

`print Dumper(\$po); # Why??` I wanted to be doubly sure! Truly, it was an artifact from a "`print Dumper(\%hash);`" test. It has been corrected.	[reply] [d/l] [select]
