The only thing I really miss in the default Ruby hash is property access for keys like JavaScript has.

I know, I know, OStruct does this but it's not the thing that gets built from hash literals so it's less convenient.

It's a minor quibble

OpenStructs are ungodly slow anyway. If you want such accessors you probably want a plain Struct anyway and not mix hashness and method accessors. You can even define additional methods on structs:

    Foo = Struct.new(:a, :b, keyword_init: true) do
      def frobz
        ...
      end
    end

Structs are quicker to instantiate than classes but slower to call methods on, so if you instantiate a lot but seldom call they're great. Otherwise a class is better.

The new Data class in Ruby 3.2 also does the job (although it's intended for immutable data)
