Your syntax is a little off...
$intHash1Ref = {};
$intHash2Ref = {};
# note use of parens, not curly braces
%containerHash = (hash1 => $intHash1Ref, hash2 => $intHash2Ref);
The parens store a list into %containerHash, the curly-braces were storing a
hash-ref.

Subject: adding hash reference into hash
Hi,
I'm just trying to make a structure with a hash containing some
references to other (yet unused) hashes.
So what I wrote this:
$intHash1Ref = {};
$intHash2Ref = {};
%containerHash = { hash1 => $intHash1Ref, hash2 => $intHash2Ref};
Then when I try to have a list of keys to that containerHash:
print keys(%containerHash);
I get some hexadecimal values like:
HASH(0x813f9b0)
How can I manage to do that cleanly?
I'm searching in "Programming Perl 3th Ed." for that but I don't get
it... yet.
Yannick
