How should I change the default, and use list instead of intlist? But see

My goal is to provide a Befunge interpreter that just does the right thing
out of the box - that is, that does not need to patch Parrot in order to
function.
Anyway, maybe the correct answer would be to create my own pmc class that
would derive from your list, and that has the behaviour I want... But then
the question would be: how should I do that?
And remember that I want to have a Befunge interpreter that works "as is".
ie, that uses only Parrot basics, and does not need to recompile...
