Overeager autocomplete for @. gives @__DOT__.

[haakon-e]

Cross-posted from #pluto channel in slack.

I'm on Pluto v0.20.3 (but feel like it's been like this for a few versions), and notice consistently that @. autocomplete to @__DIR__., unless I type the . very quickly after typing @. Has anyone else noticed this?
(in the movie I only type @ then . , but do so either "slowly" or "quickly")
