Add `baseProperty`.
Add `baseMatches`, `bindCallback`, and `setCallbackData`.
Add `baseMatches` and remove `_.matches` from  `uninlinables`.
Make `_.unzip` use `baseProperty`.
Change `setCallbackData` to `isBindable` and use `bindCallback` more.
Whitespace nit.
Tweak the order when `complexVars` are checked in `matchVar`.
