Same here. BTW I'd like unittests that "must not compile" and unittests 
that "must fail dynamically".

For the former case, the compiler should cooperate:

@incompilable unittest { ... }

fails if it passes compilation. So the compiler must know about that 
attribute.

For the latter case, no change in language is necessary, only in druntime:

@mustfail unittest { ... }

Would love these two.
