Detect a function of a given module?

Thanks for creating these codemod utils and example! 🙂 Really cool.

I'm exploring if I could use this codemod for the migrations of BuckleScript `Js` modules proposed in https://github.com/BuckleScript/bucklescript/issues/2975. I wonder how I could approach the detection of usages of some specific functions in `Js.X` modules:

If I use syntactic analysis (e.g. use `Pexp_ident` to match against the function names) it might not be effective in all cases, for example the function can be called with `Js.Array.map` or just `map` if the `Js.Array` module has been opened before.

There is `getExprType` which is awesome but it just works at the type level, so I wouldn't know which function has been called, only the type of the expression.

Is there an approach that I'm missing to do this kind of detection in an accurate way?

Examinez les utilitaires de codemod et l’exemple, puis étudiez la manière dont Pexp_ident et getExprType traitent des appels tels que Js.Array.map et un map provenant d’un module ouvert. Comparez si les informations de syntaxe et de type disponibles permettent d’identifier précisément la fonction appelée. Le travail est terminé lorsqu’une approche de détection fiable, ou la limitation qui l’empêche, est documentée.
