[J3] [EXTERNAL] Generics for Go

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

I am nominally on vacation (staycation) for the next two weeks.   I’ll generally be around, but don’t be surprised if I end up not dialing in because I’ve found something outside to do.

- Tom

PS I’ll shortly be sending out a separate poll for choosing our November meeting.

Awesome, thank you Damian.

I setup a pool for this week:

Anybody interested please note your times, I will announce on Tuesday morning when we'll do the call.

Hi Bob and Vipul,

a previous effort to do so, but
apparently it was too ambitious.


Thanks for the link. I read it and my understanding of it is that they are doing  templates + strong concepts (using C++ terminology), which we have determined in the Generics subgroup is the way to go. The Go proposal shows on an example how it differs from C++ templates.

They specifically show that the constraint causes the compiler to check both the user code (instantiation) and the library code (generics code). That's called the strong concept in C++.

Is anybody interested in having a video call next week to make some more progress on generics?

Here is our current status:
