It's similar but different. With autoloads, when you first use a
function in a package, the package loads, Emacs stalls. With defer, it
loads in the idle cycle.

I also use it for global minor-modes like Helm. Normally, it's loaded by
the time you want it.

idle time, rather than run time. It's a good compromise.
