JP7-027 20.3.4.1 p3 [out.ptr.t] Class definition after example

[jensmaurer]

There should be a class template definition before the example.

Move class template definition before p1.

[jensmaurer]

This is increasingly common style: Present an example how to use a facility before defining the facility. We do that in [ranges] quite a bit.

@jwakely to chime in.

[jwakely]

Reject

[jensmaurer]

There was no consensus for a change. Introducing a facility by showing an example use is considered reader-friendly.
