There's also multidimensional hashes [...] They're kinda weirdly implemented and not really used much.

Basically, all list elements are joined by $; (defaults to \034 = \x1C = ASCII FS) before using them as hash key. This is not multidimensional, it is just a poor emulation used mainly for awk compatibility.

Problems:

The list elements must not contain the value of $; or else your data becomes garbage.
Of course, you should not modify $; at runtime or else your data becomes garbage again.
keys and each return the joined keys, not lists of key parts. There is no automatic split.
The syntax does not work for slices.
