no, there is. I might not be a full design by contract scheme, but it's good
My approach relyes on macros just like the one find in the boost yahoo
dierctories, and one can choose
to to throw exceptions or call normal 'assert' like functions which exits

There is very little automation, except that one can make for class

class Base_base
    virtual void foo() = 0;

class Base
Base_base* obj_;
   void foo()

I code the class invariant as a function which is at least called from
the constructor body; Actually it should be called from any
public non-const function.

I can set up a link with my macros so you can see it, but it pretty similar
to that at yahoo except
for its style: I don't use capital letters for the macros but think of the
words as reserved and I always pass a comment
along with the asssertion, eg.

require( "valid pointer", ptr );
