Hi Andrey,

Unfortunately, I don't believe I can edit mailing list posts even on the
Google Groups page. Sorry to have missed your post originally!

2020-06-27 Thread t hepudds
Hi Tyler,

I just wanted to say a quick thank you for pulling those references together 
and your thoughtful response in this thread. 

Hopefully the time you spent doing that will help additional gophers as the 
generics discussion continues on this list.

Regards,
thepudds

Hi Rob,

This topic has been discussed many times on this list, so it's probably
best to look at and post in one of those threads. Let me take this chance
to collect as much information about this issue as I can in a single post.
Unfortunately, discoverability can sometimes be hard on mailing lists so I
don't blame you for not seeing all these.
