Using increment/decrement in a line?

[Vermoot]

Hi! First of all, love the plugin.

I was wondering if there might be a way to use the increment and decrement functions in a single line. Say I have:

list = { 1, 2, 3, 4, 5, 6, 7 }

and I want to turn it into

list = { 2, 3, 4, 5, 6, 7, 8 }

This example is easily solved in other ways, but you get what I mean.

How can I do that? Thanks!
