RecursionError: maximum recursion depth exceeded when calling `to_dict()` on `JsObjectWrapper`

[tristanlatr]

Hi,

Thanks for this software, I'm hoping I can get the minified source code of https://github.com/olivernn/lunr.js translated to Python but I'm running into an error when trying to use the main lunr function.

Here is my code:

>>> js2py.translate_file('./pydoctor/templates/lunr.min.js', 'lunrlib.py')
>>> from lunrlib import lunrlib
>>> type(lunrlib)
<class 'js2py.base.JsObjectWrapper'>
>>> import sys
>>> sys.setrecursionlimit(12000)
>>> lunrlib.to_dict()
Traceback (most recent call last):

RecursionError: maximum recursion depth exceeded while calling a Python object

The minified code can be found here: https://github.com/tristanlatr/pydoctor/blob/js-search/pydoctor/templates/lunr.min.js

The docs of lunr: https://lunrjs.com/docs/lunr.html

I suspect the issue comes from the fact that lunr name is namespace but also a function...

It would be really appreciated if we could find a workaround for this bug! Maybe if 2 names are conflicting, just rename it with an index appended and leave a warning ? or maybe there is way to make it work ?

Thanks!
