Discussion:
The requirement "P shall have a declaration of the form typedef X distribution_-
type" effectively makes the use of inheritance for implementing distributions very inconvenient,
because the child of a distribution class in general will not satisfy this requirement. In my opinion
the benefits of having a typedef in the parameter class pointing back to the distribution class are
not worth the hassle this requirement causes. [In my code base I never made use of the nested
typedef but on several occasions could have profited from being able to use simple inheritance for
the implementation of a distribution class.]
Proposed resolution: I propose to drop this requirement.

Close NAD for the reasons given in N2424. In practice it is not inconvenient to meet these requirements.
Proposed resolution:
See N2424 for the proposed resolution.
