Indexing is just multiplexing (more properly demultiplexing) and multiplexing/demultiplexing is just more combinatorial logic.

Yeah. But for a function with parameters there needs to be a way to associate values with parameters. There are different ways to do that, but even a static global would be accessed by address.

At the gate level, "accessing by address" is demultiplexing. It selects one of n output lines with log2(n) input signals. https://en.m.wikipedia.org/wiki/Multiplexer#Digital_demultip...
