[J3] [EXTERNAL] Re: Slides available for your preview - Part 2 of the Generics Tutorial today at the J3 plenary

[Clune, Thomas L. (GSFC-6101)]

Disagree that it is the only way.    But agree that it is one way.

I have some concerns about the parameterized modules approach,  but we may well end up there.

For the moment we are exploring and your argument below that “One needs to have generic encompass everything in a module.” Is unsubstantiated.  (And a bit hard to believe given approaches in other languages.)

This approach to generic is wrong headed. It is not useful to have "generic" encompassing a few requirements. One needs to have generic encompass everything in a module. Otherwise, the incomplete and inconsistent integration of parameterized types and type-bound procedures, about which Richard Maine warned twenty years ago, is not addressed.

Go back and look at 04-383r1. It addresses all of the issues that Magnus discussed in Tokyo.

Fyi, a copy of the slides for part 2 of the tutorial on Generics is available, if you're interested in taking a look ahead of today's meeting.

It is under Meeting FIles -> Tutorials and file named, "Part 2 Tutorial Generics.pdf":
