I'm no inner-compiler developer, but it probably depends on what you want to
do. Just fuzzy linking trying to match undecorated functions with decorated
ones, or really evaluate the number of arguments to create the decoration on
the "header" side, and then do exact linking.
The fuzzy option is easier, but the other stuff is probably also needed for
generating libs with compatible decoration, as well as making use of the
main use of decoration: overloading external symbols on the basis of number
of parameters. (default param alike probably)
