I know a property read/write to a member of a record, if that record is a

I tested the following code, it seems fpc also allows that for classes.
type
TFoo = class
protected
cn: Integer;
end;
TForm1 = class(TForm)
private
a:TFoo;
public
property b: Integer read a.cn write a.cn;
end;
I have not tested it at runtime.... I assume it depend on a being initialized
with an instance.
Question, is that allowed by intention? That is can I trust that it will be
supported by future fpc versions?
Or is that a missing check somewhere, and bay stop working in future?
I think the latter, unless this was added recently as a feature.
At least in RTTI there is no support for getting/setting fields
as part of a class-typed field?
