the thing i hate most about golang: no generics. the thing i love most about golang: super fast.

Just yesterday, I discovered their date parsing, which uses example based formats. It's pretty cool. Instead of the typical yyyy-mm-dd format nightmare, you would do 2006-01-02. The reference date is the key.

Generics have their use cases, but in general they are overrated. Especially in (but not limited to) the DevOps area, I bet that 99% of the code needs no generics at all.

Having said that, I would not complain if the concept of Ply (https://github.com/lukechampine/ply) becomes part of standard Go.

You're right. Although a lot of people have written about this limitation in the language. Applied Go has a tutorial on how to use arrays, slices, or maps as a workaround for many generics need cases, much like it looks like Ply does. https://appliedgo.net/generics/

depends on what you're trying to do with devops. If you're writing a script, I agree. Use bash anyway, Go probably isn't the thing. If you're writing a modular agent that monitors a running system, then generics would be pretty nice.

Ply looks interesting, but still lacking for my particular use case.
