Re^2: objects are references, right?

Thanks! I've been using a more baroque version of the code I free-typed in here for a while now, and I've been checking with Data::Dumper already, but somehow I'm having difficulty with its coding style sometimes :)

This clarifies things - it's the way I thought, but sometimes it's nice to have confirmation.

I tend to use the `x` debugger command, which in some cases makes it more obvious: `DB<2> x $child 0 Node=HASH(0x1c58f28) 'parent' => Node=HASH(0x1d9b770) 'parent' => undef DB<3> x $parent 0 Node=HASH(0x1d9b770) 'parent' => undef` [download] You can see by the hash addresses that `$parent` and `$child{'parent'}` point to the same hash. This is not immediately obvious with `Data::Dumper`. -QM -- Quantum Mechanics: The dreams stuff is made of	[reply] [d/l] [select]
