I don't understand the point of it when the `.map(&:upcase)` syntax is shorter. This just seems like yet another syntactic sugar Rubyism that doesn't really add anything.

If it's an alternative to the `|x|` syntax when using only one block variable, then I like that.

`arr.map { it.thing.blah.stuff }`

The `&:` doesn't work in that context

Not to point any fingers, but shows that the previous commenter have not struggled with this :)

&: is very nice, but not enough.

That only works when calling a method on the things you’re iterating thru, it is a replacement for the single variable block example you gave there
