Was just playing around locally and found one of the undescribed Irb improvements is a drop-down with autocompletion suggestions nice!

I haven't had a chance to try yet, but I'm hoping some of the irb regressions that began around 2.7 are fixed. Try pasting an array or hash with 1000 or so elements. In 2.6.x it's instantaneous, in 2.7.x it can take minutes--
