digitalmars.D.bugs - [Issue 18228] New: this(this a){} doesn't generate postblit ctor;

https://issues.dlang.org/show_bug.cgi?id=18228

          Issue ID: 18228
           Summary: this(this a){} doesn't generate postblit ctor;
                    this(this){} does
           Product: D
           Version: D2
          Hardware: x86
                OS: Mac OS X
            Status: NEW
          Severity: normal
          Priority: P1
         Component: dmd
          Assignee: nobody puremagic.com
          Reporter: timothee.cour2 gmail.com

in all of D, parameter names are optional (if unused) eg: `fun(int a)` <=>
`fun(int)` but not for postblit:

```
struct C{
    version(v1)
    this(this a){}

    version(v2)
    this(this){ }
}
pragma(msg, "C: " ~ __traits(allMembers, C).stringof);
```

dmd -o- -version=v1 main.d
C: tuple("__ctor")
dmd -o- -version=v2 main.d
C: tuple("__postblit", "__xpostblit", "opAssign")
