Yes. But it works only partially. For example the following
code is not compilable:
Well, I wouldn't know either what you expect :)
I expect that compiler will choose DoTest with ansistring
parameter in that case.
What rule do you apply to say this?
Compiler treats '1234' as ansistring constant. Therefore ansistring
overload must be choosen here.
No, '1234' is taken as generic string constant.
Yes, I just tried to explain possible logic :)
Also the following code is not possible currently:
//------
operator := (const s: ansistring) r: TUTF8String;
begin
end;
operator := (const s: TUTF8String) r: ansistring;
begin
end;
//------
It makes implementation of utf8string impossible using this
approach...
//------
type
TUTF8String = type ansistring;
procedure DoTest(const s: ansistring); overload;
begin
end;
procedure DoTest(const s: TUTF8String); overload;
begin
end;
begin
DoTest('1234');
end.
