Re: work around for static vars and singleton constructors not inheriting properly?

[simonm]

Sorry for the late reply, but I don't think Class::MethodMaker will do this for you.

My Class::MakeMethods module does have something close to what you want:

  use Class::MakeMethods::Template::ClassVar
    'instance' => 'my_singleton',
    'scalar' => 'my_static';

Those methods store a value in a per-class package variable, so each subclass and its instances share a common value without influencing the superclass and other subclasses.

For the static method, if you'd like the subclasses to default to sharing the superclass value and only override it in a few specific subclasses, use Template::Inheritable instead of Template::ClassVar.

I haven't tested the combination of Template::ClassVar and instance; please let me know if it doesn't work as expected...
