If you want speculation, how about..
You used the array reference as a KEY in a hash, and are trying to
deref the value of 'key'.
Eg,
[EMAIL PROTECTED] = [EMAIL PROTECTED];
for( keys %X ) {
print $_->[0];
}
Anything which is used as a key becomes a string, and can no longer be
used as an actual reference. Remember 'ARRAY(0x22bdfb0)' is the scalar
representation of a reference, not an actual reference. You cannot
convert the scalar back to a reference. You can try, with something
like '$ref = unpack("p",0x22bdfb0)' and I'd love to know if it worked.
