In over a decade of driving, moving, and everything in between I have never needed a heavy duty truck like a Ford F-350, so clearly they aren’t useful and Ford should stop making them, right?
Oh construction workers might complain, but they could just use dump trucks to haul their heavy loads. And farmers might have issues, but they have tractors which could suffice. So what is the big deal? Let’s stop making those trucks!
Clearly this is an insane argument, so why is it constantly being used as a reason to end discussions about generics in Go?
Just because you don’t personally experience a problem doesn’t mean it is nonexistent.
There are many problems where generics would be useful.
Generics may not be the best solution, but they are better than anything that currently exists. This is where the discussion should start.
What are those problems?
What have people tried so far? Why has it failed or why would generics be better?
What other alternative solutions could we consider to solve the problem?
In other words, if you don’t agree with the addition of Generics in Go stop telling everyone, “I haven’t needed them in 3 years” and instead start reading the experience reports and helping people come up with solutions that don’t involve generics and aren’t a nightmare to maintain.
