If your unit tests take hours to run, then you aren't going to get
anything useful from the ABC requirements for hours either (unless you
are pre-instantiating everything you are going to use during program
execution, in which case this could become your unittest).

Please remember that this isn't about Java style type checking and
verification during compilation.  This is, strictly speaking, ABC
checking on object instantiation, method invocation, and possibly even
argument verification.  This isn't the magic bullet you are looking for
(you'll have to go to one of those static typed languages for that).
