Calling a function upon set command

I'm swapping some mappings on my keyboard to make it easier on my wrist, but I wouldn't want others to be surprised if they open vim on a computer I had been working on.

So I put these mappings inside a function in my .vimrc so I can selectively enable the mappings.

My question is, how can I tell vim (in the .vimrc file) to call a function if I :set a variable?

Something like :set wrist and it would call SwapKeysForWrist.

Note: I know I can give the function a simpler name and call it, for example :call Shahbaz(), but that requires me to use shift three times (besides :) which is what I'm trying to avoid. In fact, the function swaps the digits with their alternative keys (since I use those symbols much more often than actual numbers during programming), and typing parentheses (added that I'd be holding shift) does strain my wrist.

You cannot define your own :set names, you can only use mappings or custom commands.

I would suggest using a custom :Wrist command; it's short to type and should be easy for you to remember. If you want to get around the uppercase W, you need to use a :cabbrev or the cmdalias plugin.
