Great list! Reminds me to check out more of the new stuff in 1.25.

The one thing I wish Go had more than anything is read-only slices (like C#).

The one thing I wish more other languages had that Go has is structural typing (anything with Foo() method can be used as an interface { Foo() }.

In Go, string effectively serves as a read-only slice, if we are talking about bytes.

ReadOnlySpan<T> in C# is great! In my opinion, Go essentially designed in “span” from the start.

System languages from 1980's already had the span concept.

One way that you will find it is that they used to be called open arrays in some of them.
