Yes.
Can use lambda,functor,static function if first argument is same type.
state["A"].setClass(kaguya::UserdataMetatable<A>()
.setConstructors<A()>()
.addStaticFunction("lambdafn", [](A* self,int v){self->setValue(v);})
);
local a = ABC.new()
a:lambdafn(3) --equal setValue(3)
a.lambdafn(a,3) --equal to above

addStaticFunction may not the best name for it situation. I prefer to addMemberFunction.
from kaguya.
If implement addMemberFunction for global function, need first argument type check.
but it implement for C++03 is difficult.

Yes, another question:
When class has setter and getter function, can I treat it as property?
class Class
{
void SetValue(int value);
int GetValue() const;
};
.addProperty("value", &Class::GetValue, &Class::SetValue)
from kaguya.
Can not now. Try to make because it is easy.
from kaguya.
Thinks, but as convention, it is better make getter as first argumention.
template<typename GetType, typename SetType>
UserdataMetatable& addProperty(const char* name, GetType(class_type::*getter)()const, void (class_type::*setter)(SetType) ) {}
from kaguya.
It's changed.
from kaguya.
Great!, but
template<typename SetType, typename GetType>
UserdataMetatable& addProperty(const char* name, GetType(class_type::*getter)()const, void (class_type::*setter)(SetType))
First template arguments is SetType, It is misleading.
