It has always been in NMock although I think overusing this approach is 
probably
a Bad Thing - interfaces are better.

In terms of the semantics though, I would suggest that the constructor 
could be
called when the mock is created :

IMock mock = new DynamicMock(typeof(ClassWithFatConstructor), param1, 
param2, param3);

since we can only initialize the instance once, and it is possible and 
legal to
re-use the mock instance:

a.Foo = mock.MockInstance
b.Bar = mock.MockInstance

Note that in this case there is still only 1 underlying mock object, not 2.

Alternatively, we could introduce an explicit CallConstructor() method?

DynamicMock mock = new DynamicMock(typeof(ClassWithFatConstructor));

mock.Construct(p1, 2, p3);

and it would then be an error to call this method more than once.

I prefer the first option though
