[erlang-questions] : Sending funs between nodes

[Raimo Niskanen]

Since the shell emulates expressions it does not compile funs
- it emulates them too. And that is done by having a bunch of
compiled shell funs; arity 0..20 something. These shell funs
take the real fun code to emulate in their environment.

So they look like funs, but are fun instances that emulate
the fun you defined in the shell.

That also means that they are compiled on all other nodes if just
the same version of the shell module is loaded on the other nodes.
