> Did Bram Moolenaar tell you that? Otherwise, none of us know what motivated him. I don't think this is a subjective matter? The sequence of events was: 1. async feature was proposed in 2014 and earlier, Bram was opposed to the idea in general 2. neovim was created to integrate async and other improvements 3. lots of plugins started supporting neovim's async 4. vim comes out with its own async feature You're welcome…
post hoc, ergo propter hoc -- this is a logical fallacy
1. async feature proposed and implemented in neovim
2. vim comes out with its own async feature.
shazow's post has significantly more evidence of neovim's responsibility, enough that it isn't a fallacious argument. It isn't definitive proof, either.
