I found a way around this:

cppcode = """\
class MyExpression : public Expression
{
public:

  MyExpression() : Expression(%d) {}

  ...

};"""

f = Expression(cppcode % mesh.geometry().dim(), V=V)

:-)

But the other problem still remains: not being able to send in a
Function as an argument to a member of MyExpression.
