Yes, we might need to think about that, although it's not completely
obvious which parameters need to be passed to which constructor.
Anyway, one can solve this problem readily by creating the document
and page instances explicitly (untested!):
from pyx import *
c = canvas.canvas()
# create most magnificent drawing...
# ...
# ... and wrap it by yourself
document.document([document.page(c)]).writePDFfile(title="my opus magnum")
Cheers,
