What functionality do we want from the compiler/vm modules?
In my own mind, the compiler is just a black box, that wants the name of a
file to compile, and returns the compiled code together with a pointer (or a
handle or a name) to the VM needed to interpret the code.  More or less the
same with VMs, you give it a piece of code to interpret, and it returns a
succes/failure code.
