2. The semantics is the same unless warnings are enabled with

3. In "-w" mode, semantics are changed in that the type of the
comma operator is NOT the type of its last expression, but

4. Later on the warning will be promoted to a deprecation
followed by removal from the language.
Semantic changes based on warning or deprecation flags are a bad
idea, because it breaks code unless warnings are disabled.
The cycle should go warning => deprecation => semantic
change/removal, each step taking 6 month.
