vi editing is in my fingers by now but one unixy “good taste” I missed in
it is composability. External filters didn’t quite hit the right spot. As an
example, you can map a key to do a sequence of operations but you
you can’t then use it in conjunction with search to repeat them over a
range of lines. Eventually nvi added optional support for scripting but
full power of a general PL is not quite what I wanted. And vi didn’t have
to become another Emacs. May be an ability to define new commands,
If/while control structures, expressing its notion of objects (lines, para,
Sections etc) in this DSL and an ability use user commands just like
builtins would’ve gone a long way. Of course, the hard part is coming up
with a clear conceptual model.

And if you can use the tools, without having to think about them and they pretty much are what you rely upon everyday, you are getting close to my ideal of 'good taste.'
