This is perhaps a crazy question! Forgive my ignorance!
I start with something like this:
iex> f = fn -> IO.puts("hi") end
#Function<45.79398840/0 in :erl_eval.expr/5>
I am wondering if I know 45.79398840/0, how is it possible to recreate the function? Something like
new_f = make_function_somehow(45.79398840/0)
new_f.() # "hi"
Is this possible? Is it only possible on the same node? Or not possible at all? Or is it possible to retrieve the original function definition (fn -> IO.puts("hi") end)?
Thank you in advance!

It is not possible.

Thank you for clarifying!

Probably not what you are looking for based on your first post, but just so you know, you can “store” a more “serializable” function reference using the module and function name as an atom, for example:
