Silently enters 'void* this;' pointer making compiling error out. Current beta
(v2.061, windows 32bit)

 Only by using traits will the problem show itself.

[code]
  static assert(__traits(compiles, {
    union xxx {
    int i;
    //bitfields will make such functions...
    mixin("int geti() @safe const nothrow pure {return i;}void seti(int ii)
@safe pure nothrow {i = ii;}");
    }
  }));
[/code]

output:

test.d(??): Error: static assert  (__traits(compiles,delegate pure nothrow
@safe void()
{
union xxx
{
int i;
mixin("int geti() @safe const nothrow pure {return i;}void seti(int ii) @safe
pure nothrow {i = ii;}");
void* this;
}
}
)) is false
