Parsing bug?

[Jean-Louis Leroy]

import std.traits;

unittest
{
   struct attr;
   void foo() {}
   ReturnType!foo bar(int a) {}
   void baz(@attr int a) {}
   ReturnType!foo blah(@attr int a) {}
}

dmd -c -unittest bug.d
bug.d(9): Error: found `blah` when expecting `;` following 
statement
bug.d(10): Error: found `}` when expecting `;` following statement
bug.d(11): Error: found `End of File` when expecting `}` 
following compound statement

This goes away if I remove `unittest { }`.
