This is still true.

So, to be able to have **multiple processes** at the same time, there has to be a **single process listening on a port** that then transmits the communication to each worker process in some way.

length of the following data (so the value can be skipped if it cannot be
stored), followed by the usual encoding of concrete (dynamic) value stored in
the interface value. (A nil interface value is identified by the empty string
and transmits no value.) Upon receipt, the decoder verifies that the unpacked
concrete item satisfies the interface of the receiving variable.

If a value is passed to [Encoder.Encode] and the type is not a struct (or pointer to struct,
