When I’m editing, I want to have access to some “built in” functions that should be available in the Editor (Completion and Definition) without importing.

The code for those built ins will be something like this:

importnumpyasnpmyHeaderVar=123defmyFunction(x):returnnp.abs(x)

And in the editor itself I will have:

mylist= [1,2,3,4]myFunction(mylist)some_value+=myHeaderVar

This is just a silly example to capture the idea. When I start typing the myF.. it should provide the completion for the myFunction as it is present on the "built in headers".

So my question really is, there is something in the pylsp that support this? Like, loading this header.py from the same workspace that the main.py is and making the content of tha file available?
Or a way to provide the content of this Header.py to be used together with the code from main.py acting as dictionary for the completion and linting checking?
