experience report: mistyping fun delimiter

[disconcision]

Below I accidentally typed fun as dun:

If I go back and make the correction, the resulting state is:

Not a bug, as the current policy is that expansion needs a space, but this strikes me as maybe sub-optimal in that the editor generally conditions people that they often don't need to insert spaces themselves, so obligate spaces for expansion might chafe a bit during corrections

I'm thinking a combination of clearly indicating reserved keywords as being in error and letting Tab do the expansion (possibly indicating this expandability via Tab explicitly a la Cursor) should help here

[disconcision]

that would help mitigate it for sure... remind me of why you're not keen on triggering expansion on move-away instead of space/tab?
