This is rather crude, but:


There is a very wide variety of programming languages in which
simple procedure/function calls with positional parameters can
be written identically. With just about any generator, you can
put in semantic actions that consist only of a call that is
syntactically valid in many languages. Then write the definitions
of the actions in your choice of language and compile together.


Obviously, several details have to be treated with some care.
