[00:17] <Longor> I think the points was that there can be objects with completely unknown data layouts, and these might have to be sent across the network or stored somewere.
[00:17] <Longor> 'unknown data layouts' = A script creating objects of some kind.
[00:18] <Longor> The script might want to save these objects somewere, and do that in a compact (binary) fashion.
[00:18] <Longor> binary because the script might want to store several thousand objects of all kinds.
[00:19] <Longor> 'of all kinds' again being 'unknown data layout'.
[00:19] <Longor> You could go and use JSON, but that's a waste of memory and potentially slow with lots of data.
[00:20] <Longor> Scrap potentially; It IS slow to parse in comparison to a binary format.
