           Summary: assignment is sometimes still accepted as a condition

Problem seen with:  DMD64 D Compiler v2.067.1

bool cond = true;
do {
   // stuff
   } while (cond = false);

yields:

Error: assignment cannot be used as a condition, perhaps == was meant?

But:

bool cond = true;
do {
   // stuff
   } while (cond = false, cond = false);

passes the compiler without complaint, even though it also uses an assignment as a condition.
