    So, if the output produced of the compiler originates by a method
    dispatched on a
    subclassed object it would be under GPL?

I do not follow you.
I am not sure what scenario you mean.

There are two questions here (and in any such case): who holds the
copyright, and whether there is any constraint on the license that the
copyright holder can release under.  What I spoke about is who holds
the copyright.

    What of cases where one or more methods so specialized act in concert to 
    data from some other source(s) where these sources are extraneous to the 
    handlers - e.g. the GPL'd objects/methods?

    data -> object -> method -> compiled-output

That is very abstract.  It is hard to consider these issues in the abstract.
Only a concrete scenario has all the details that affect the answer.
