Fwd: access enclosing class name in a %macro to allow defining attributes without having to use the %attribute macro

Greetings

Question: can a %macro in SWIG somehow access the name of the enclosing
class type in a statement like %mangle(...)?

The objective here is to avoid having to use the %attribute macros
I would prefer to write hpp files as follows and just %include them without
any need for %attribute

// foo.hpp
class Foo {
  READONLY_PROPERTY(Bar, bar);
};

Following the technique used in attributes.swg I came up with the following
possible definition for a READONLY_PROPERTY C++ macro.
The only issue is the %mangle(Class) statement. If I could access the
enclosing class name, then this would work quite nicely.

Thank you for any advice you can provide


#ifndef SWIG

#define READONLY_PROPERTY(Type, Name) Type Name() const

#else // SWIG defined

#define READONLY_PROPERTY(Type, Name)
               \
  %ignore Name() const;
               \
  Type Name() const;
                \
  %immutable Name;
                \
  %extend {
               \
    Type Name;
                \
  }
               \
  %{
                \
    template < class C > inline Type %mangle(Class) ##_## Name ##
_get(const C* self_) {   \
      return self_->Name();
               \
    }
               \
  %}
