This was a fun hack over the holidays. This provides `eye` for interactively viewing objects in the REPL. Use it when you might use `dump` or `varinfo`. Browse modules, type trees, expressions, or other complex objects. Use arrow keys to expand subobjects and hit `enter` to select and return the item. Toggle between showing properties and fields (`f`). Show documentation (`d`). Show `methodswith` on objects (`m`).

Here’s a demo:

Fantastic. Any chance `eye` gets renamed to something else? For instance, `inspect`, or `eyeball` or something like that.

`eye` might be confused with identity matrix, e.g. FillArrays.jl exports `Eye`.

Or that matrix shouldn’t be called `Eye`, that’s a nonsensical matlabism (sorry) for identity matrices we got rid of sometimes ago.

At this time, I’m not inclined to rename `eye`. I like that it’s a short name which is nice for frequent interactive use. The Matlab history of `eye` can cause confusion, but that naming is bad, and Julia removed it’s own version of `eye` a while back.
