urgh; I feel that the last thing we need is to couple our editors even more strongly to the flavors of the month (and 500mb+ of dependencies). I wish these things were more ecumenical...
We are speaking in a context set by vi/vim (remember, that was the jumping off point for promoting yi here).
If you cannot think of at least one language which is older and a better common denominator than Haskell (both at the binary level and at the interface presented to programmers)... I don't know what to say.
What actual reason do I have for switching from vim to yi? Just because it's written in Haskell and that obviously makes it better, or what?
I... have absolutely no idea what you're trying to say. It's not worth ever using a language if there's an older one around? Are you saying you don't want to switch editors unless the new one is written in FORTRAN?
