Since __ctfe is so magical and unique, it seems justified to give it one more
special case. Other approaches I tried (changing the storage_class of __ctfe) 
were far more complicated.

PATCH expression.c, VarExp::semantic(), line 4397.

+            /* Magic variable __ctfe never violates pure or safe
+             */
+            if (v->ident == Id::ctfe)
+                return this;

            /* If ANY of its enclosing functions are pure,
             * it cannot do anything impure.
             * If it is pure, it cannot access any mutable variables other
             * than those inside itself
             */
