Also consider using:


which works cleanly also when  \thesubject  has been defined
already, by a package or document-class.

This is particularly useful when you need to use the same
coding in different contexts, each requiring different packages
or classes, but you don't have full control over all of the
contexts (e.g., because other people use some of them too, and
they would not be happy with you messing with vital packages).

Another useful trick is:


when you know that \subject  cannot be used until the body
of your document.

This way you are free to provide a default expansion for
  \thesubject ,  but it doesn't matter if you do not do so,
or if you later comment it out.
