Re: Reference curiosity?

To elaborate on what borisz said -

Your second example does display the appropriate run-time error messages:

Global symbol "%hash" requires explicit package name at test-hashref.p
+l line 6.
Global symbol "%hash" requires explicit package name at test-hashref.p
+l line 6.
Global symbol "%hash" requires explicit package name at test-hashref.p
+l line 6.

This is easily corrected by changing line 6 to:

print "$hash->{A} $hash->{B} $hash->{C}\n";
[download]

which prints

1 2 3
[download]

as expected.
