Indeed this one is nice too. And quite simple to use compared to several other solutions :)
I'm always astonished by the incredible number of code generation solutions that Go developers have implemented to emulate strongly-typed generics in Go. In my own case, I've opted for an all-in-one tool which solved all my needs (genericity, free-form macros, conditional compilation, inline HTML templating, indentation style, etc) at once, but obviously there are already many ways to achieve almost the same result by combining several existing tools :) On Tuesday, March 26, 2019 at 10:44:19 AM UTC+1, Michał Matczuk wrote: > > You may be also interested in https://github.com/mmatczuk/go_generics (the > credit goes to Google). > > With it you can write a generic code that actually compiles and change the > types later ex. > https://github.com/scylladb/go-set/tree/master/internal/set > > W dniu poniedziałek, 25 marca 2019 15:58:03 UTC+1 użytkownik David Skinner > napisał: >> >> I am very, very, old school, grew up with ASM and Macro Assembly.
