DC> There would be a 'contract' pragma:

DC>     use contract qw("safe-coding practice");
DC>     no contract qw("debugging");
DC>     no contract;    # turn everything off (production code)

One issue that bothers me with this. Even though it is a _minor_ edit,
I never like to twiddle a working piece of code. No contract should
be the default, and during testing it should be overridden from the
command line.
