Erasure: how we got the generics we have, or how I learned to stop worrying and love erasure (cr.openjdk.org)

A great read for folks wondering why Java uses type erasure instead of "reified" generics. For the unaware, that means that a List<Integer> is a List<Object> at runtime. I had always wondered about it and why they didn't take the alternative route. For context, C# does have reified types so the actual type parameter is available at runtime.

I personally love reading in depth discussions about counter intuitive engineering decisions like this.

Funnily enough, I typed that one in the Jerboa app, but yeah, it's not rendering for me either. 🙃

I opened a GitHub issue. I think it's probably just a config thing as they are both based on the CommonMark spec. Or maybe a nug with one of the markdown libs themselves.
