Multiuser Gno REPL

[moul]

We can create a proof of concept that showcases the manipulation of Go objects by multiple individuals without relying on a blockchain.

This demonstration would effectively illustrate a crucial concept for Gnolang without explicitly discussing Web3.

Being inside a Gno/Go VM.

Related with #4, potentially an alpha version of it.

So are you imagining something like gno repl -state /tmp/gno-state which multiple sessions of the gno repl can connect to at once, potentially, which is used to "recover" the global variable state, in the same way we do for realms?

Working on gnoverse here: gnolang/gno#1016

Will make it easy to develop the Multiuser Gno REPL interface.
