Quoting Justin (a Neovim developer)[1]:

    The msgpack API is equivalent to a REST/HTTP API that allows you to
    call other "services" (plugins) which are listening behind that
    API. Everything gets marshaled through msgpack. To make a C# function
    callable by a javascript plugin, the C# plugin would need to listen
    for an event.

    And there is certainly no "binding" of live objects

    any plugin can of course map VimL functions to its language-of-choice
    (C#, javascript, ...) functions, and those VimL functions can be
    called by other functions

    I don't agree that "the important part" is having a magic FFI that
    bridges all languages. And I do think that isolation is good.
