I often find myself using // when playing around with expressions, but it is always cumbersome to have to switch to the full notation just to apply a function of two arguments.

(x+1)^3
(x+1)^3 // Expand
Collect[(x+1)^3 // Expand, x]

I found that there is one way to do this using a pure function, though I'm not sure if this is the best way

(x+1)^3 // Expand // Collect[#, x]&
