What are the plans for `x.[1]`?

I think this came up a while ago but it’s a hard thing to search for.

Are there any plans in the language for x.[1] as an alias for getindex.(x, 1)?

I know this isn’t exactly what you’re asking, but you can achieve something similar with UnderscoreOh.jl

Thanks! Indeed this is it. Looks like there are a lot of issues to work out with regards to that feature and a lot of thoughtful discussion around it.
