Description
See example in Steps.

In the example given in Steps, I wanted to declare a Degree and Fahrenheit **record**, which can convert from one into the other.

Unfortunately, there seems to be no way to declare forward records, just as I can do with forward class declarations

Kindly implement forward record declarations in the language.
Steps to Reproduce:
I cannot declare forward class records like so,

Degree = packed record;

Fahrenheit  = packed record(IConvertible)
    class operator  Implicit(AValue: Degree): Fahrenheit;
end;

Degree  = packed record(IConvertible)
    class operator  Implicit(AValue: Fahrenheit): Degree;
end;

But I can declare forward classes like so,

type
Degree = class;

Fahrenheit  = class
    class operator  Implicit(AValue: Degree): Fahrenheit;
end;

Degree  = class
    class operator  Implicit(AValue: Fahrenheit): Degree;
end;

class operator  Fahrenheit.Implicit(AValue: Degree): Fahrenheit;
begin
end;

class operator  Degree.Implicit(AValue: Fahrenheit): Degree;
begin
end;
