Interesting question, though not directly Perl related...
vi(m) is certainly not my area of expertise. I did a quick search and did not find an answer but I think
you may find that the individual who wrote the following post might be able to help you with
this:
This guy seems to know his stuff regarding vi(m) and seems to be interested in making it work with Perl.

I do understand having spent a lot of time with a given editor/dev environment and wanting to enhance it, only to find that

Best of luck with this and I hope you find this helpful.
