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?

Revisa las utilidades de codemod y el ejemplo; después, investiga cómo Pexp_ident y getExprType manejan llamadas como Js.Array.map y un map de un módulo abierto. Compara si la información de sintaxis y tipos disponible puede identificar con precisión la función llamada. Se considera terminado cuando se documente un enfoque de detección fiable o la limitación que lo impide.
