What is R supposed to be set by default on this snippet?

[Casey Brooks]

Yeah, the documentation is a bit confusing for delegates. thisRef will refer to the object that contains the delegate, which would be an instance of class D in your snippet.

Delegates can also be used on local or top-level properties, at which point it doesn't have a "containing object" to refer to and will be the Nothing type

That’s right! I just figured it out. What’s not clear to me is how the semantics EffectiveDate() works without doing EffectiveDate<D>() @Casey Brooks

Compiler magic basically 😉. The R type will always refer to the type of class it's contained in (or Nothing). So the compiler sees that you're calling EffectiveDate() and assigning it to a member property within class D, so that becomes the R type
