  Hmm alright, I've installed the beta. New problems are creeping 
up curiously enough. There seems to be an invisibly added pointer 
'this', which then makes a union break while using bitfields. 
This didn't break before...

  Unless I use the traits it doesn't show the problem. Any 
thoughts?

[code]
   static assert(__traits(compiles, {
     union xxx {
     int i;
     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 pu
re nothrow {i = ii;}");
void* this;
}
}
)) is false
