Perhaps if _Cilk_spawn is allowed in the grammer only in 3 specific cases it might be better to disallow it everywhere and check for it only in the 3 listed cases (whole statement, var initializer and rhs of assignment (but for the last one it has to be only toplevel assignment I guess, a = b = _Cilk_spawn foo (); is presumably also invalid, ditto a + (b = _Cilk_spawn foo ()); etc.
