If I ever finally implement reference-count deallocation of symbols, it's
going to be unique strings anyway, because it has to; else I'd have
to make a string type separate from the symbol type. I just didn't know
that it would bring Pd that much closer to Lua.
Once it's done, there is some further fine-tuning that can be done, so
that the hash-function (used for figuring out positions in the
symbol-table) doesn't take too long to compute, but at this point it's not
even worth thinking about it.
