The language I'm currently developing uses C as an intermediate.
And in this language message passing is one of the core
machanisms. And yes, of course message passing is possible, you
just may not implement it in form of simple function calling.

The runtime of my language implements a message dispatcher, that
delivers messages to each object on the reciever list. An object
can decide if it accepts the message and processes it, or if it
passes it on, or accepts and re-yields the message. For example
it is possible to send a message in a way, that it will be
passed up in the hierachy of object instances.
