@Andrew Helwer Nice! I enjoyed it. (Note that the community also hosts an online web editor that does include mathlib.)

https://leanprover-community.github.io/lean-web-editor/ (It can be a bit slow to start, because it has to download Lean and precompiled mathlib.)

Sweet, I've updated the post to use the community editor!

Johan Commelin (Apr 06 2020 at 14:59):

@Andrew Helwer Did you also see the hackernews discussion?

Johan Commelin (Apr 06 2020 at 14:59):

They spotted some typos over there

Oh yes, the error with the sigma... classic. Also fixed!
