Compilation unit contamination

[jordfras]

Is it possible to have two different custom generators for one type in two different compilation units?

I have two different tests in two different compilation units that both need to generate objects of the same custom class, but they need to generate them very differently. Is this possible?

For instance

class Vector
{
public:
  Vector(int offset, int length);
};

namespace rc {
template<>
struct Arbitrary<Vector>
{
  static Gen<Vector> arbitrary()
  {
    return gen::construct<Vector>(gen::arbitrary<int>(), gen::positive<int>());
  }
};
}

Let's say I need another generator in another test that generates Vectors with only positive offset. I cannot put the generator in an anonymous namespace and thus there will be leakage between compilation units.

Is there an established way to work around this problem?
