 From M3:

Try Except:
http://www.research.compaq.com/SRC/m3defn/html/tryexcept.html

	TRY
	  Body ...
	EXCEPT
	  exception => action; ...
	END

Try Finally:
http://www.research.compaq.com/SRC/m3defn/html/tryfinally.html

	TRY
	  statement 1;
	FINALLY
	  statement 2;
	END

might give you ideas and potential semantic issues. eg

Another key word might be trap?
