Ah - so much for precise examples :-) I meant T and a to be identifiers, i.e. the example was meant to be a real *example*, not some generic thing where T could also be int or the like. The C# spec at exactly the place cited is careful enough: It says explicitly "If x and y are identifiers, ..." - I forgot this.

Lesson to be learned: Specify examples better :-)
