Description Stewart Gordon 2008年07月11日 05:45:47 UTC

With the purported deprecation bug fixes in DMD 1.032, a number of new deprecation bugs seem to have (re)surfaced. Issue 2207 and issue 2208 are two; here is another (probably related to 2208).
----------
deprecated {
 class DepClass {}
 alias DepClass DepClassAlias; // works
 alias DepClass* DepClassPointer; // all the rest fail
 alias DepClass[] DepClassArray;
 alias void function(DepClass) DepClassParam;
 alias DepClass function() DepClassReturn;
}
----------
dep_1032_a.d(5): class dep_1032_a.DepClass is deprecated
dep_1032_a.d(6): class dep_1032_a.DepClass is deprecated
dep_1032_a.d(7): class dep_1032_a.DepClass is deprecated
dep_1032_a.d(8): class dep_1032_a.DepClass is deprecated
----------
The aliases being created are themselves deprecated, so it is within their rights to depend on deprecated stuff.
This happens regardless of whether the original deprecated type is a class, interface, struct, union, enum, alias or typedef.
This has broken the WindowsAPI project at least.

This seems to be a generalisation of #2208. It works in the pre-release of DMD1.033.
