To be correct: Result is not the name of the result value, it is an alias.
I did not dispute that. The important point here is: "an alias" to /what/?
You can still use the function name for the result, so "Result" is in fact an
alias for the function name
Result is not "an alias for the function name" because you cannot use Result to
refer to the function:
-------8<-------
function Foo: Integer;
var X: function : Integer;
begin
Result(); // ERROR
X := Result; // ERROR
end;
-------8<-------
the function name, which is the actual name for the result value.
I can get behind this notion; however, within the function, that name is
overloaded. Thus, we should not say, like Sven did, that Result aliases the
function (name); we should say, like I did, that it aliases the return value
(name).
But, conceptually, I would rather look at the function name resolving to the
return value as a backward-compatible alias, and say that Result is the true
(default) name for the return value. Such notion fits modern usage.
I do agree with your point that it should be allowed to explicitly name Result
as Result for operators, even when the Result identifier is allowed.
The score thus far: 1:1.
