I hope/pray that readline and/or editline work correctly on bash et al?
Do Windows CI services like Appveyor support WSL? If so I would hope that deploying to windows for lots of high level software is relatively painless.
Head scratcher from the video:
> What if I want to open this file in notepad?
> ... <demonstrates opening notepad from bash>
> audience applauds
Ugh, the only thing worth applause here would be if instead he had said "and we finally taught notepad how to work with different line-endings" or "and we finally deleted notepad". The demo clearly shows the shebang line mashed in with the rest of the file contents. "This was a very popular ask" -- from whom‽ To present things as a dichotomy between vim and notepad is not honest.
EDIT: comments below have clarified: the feature refers to launching Windows processes from linux ones, not notepad specifically.
