Delphi：Char和TCharArray的数组“不兼容类型”

我在下面的评论中遇到过这个不兼容类型的错误，并且从来没有为什么在Delphi 2007中没有直接支持：

I've run across this "Incompatible types" error in the comment below a few times, and never been happy with why this isn't directly supported in Delphi 2007:

program Project1; {$APPTYPE CONSOLE}

type TCharArray = array of Char;

procedure DoArray(Chars: array of Char);
begin
end;

function ReturnTCharArray: TCharArray;
var CharArray: TCharArray;
begin
  Result := CharArray;
end;

begin
  DoArray(ReturnTCharArray); // [DCC Error] Project1.dpr(18): E2010 Incompatible types: 'Array' and 'TCharArray'
end.

不应该可以使数组类型aliased其他？假设我不能改变DoArray的声明（它是第三方库的一部分），我如何编写一个函数返回一个与DoArray参数兼容的char数组？直接的函数ReturnAChar：Char;导致标识符期望但是ARRAY'found错误。我甚至尝试更改函数返回数组到一个具有varcharpram的数组的过程，但是也不允许在过程中设置Char数组参数的长度（常量对象不能传递作为var参数）。

Shouldn't it be possible to make an array type "aliased" to another array type compatible with each other? Assuming I can't change the declaration of DoArray (it is part of a third party library), how do I write a function returning an array of char compatible with DoArray's param? The straightforward "function ReturnAChar: array of Char;" results in an "Identifier expected but 'ARRAY' found" error. I even tried changing the function returning the array to a procedure with a var "array of Char" pram, but that also doesn't allow setting the length of the "array of Char" param in the procedure ("Constant object cannot be passed as var parameter").
