Assume you are a programmer and a vim beginner:
- As a beginner, you need really really a lot of time to familiar with vim built in stuff.
- There are also some plugins you can't live without them, you need time to choose and familar with them:
- plugin manage plugin
- resouce navigate plugin
- code navigate plugin.
- auto complete plugin
- snippet plugin
- syntax check plugin
- status line plugin
- color scheme plugin
The list might goes on and on, it depends on your coding language, but
most of time auto-pair is not one of them.
It's pretty easy to get overwhelmed. You also need extra plugin to make auto-pairs work with . repeat, so IMHO don't use it for the 1st and 2nd month, a few more key strokes wouldn't kill you.
Feel free to try it later.
