Comment (by jdemeyer):
Replying to [comment:3 ncohen]:
> why you replace exmples which use the "p[x]" variables with examples
that do not use this trick?
Because that trick creates variables with ''default'' parameters, which
now changed to `nonnegative=False`. So, the restore the old example, I
needed to explicitly use `p.new_variable(nonnegative=True)`.
