Re: Abstract classes

You only need to worry about the wrapper if you want to derive classes from A in Lua.

Otherwise, you can do something like this:

using namespace luabind;
module(L)
[
class_<A>("A")
    // can't bind constructor because it is abstract
    .def( "bar", &A::bar )
class <B, A>("B")
    .def( constructor<>() ) // implicit B()
];
