Imaging you are developing in the django context.
Everytime you use a variable named "request" or "response" your human brains knows that this is a subclass of django.http.HttpRequest and django.http.HttpResponse.
How to give the IDE this knowledge?
One solution is the do typehinting everywhere the veriable gets used.
But why does the human brain not need this?
Because it is intelligent?
I would not call this intelligence. There is a simple dictionary in the brain of the developer, which maps:
variable-name --> Type
And this mapping dict exists once per library.
If you are developing in the requests http lib, then there is a different mapping. Then "response" means type requests.Response.
Now my idea: Per module and/or per file type hinting from variable name.
Maybe a magic docstring in the __init__.py file:
""" variable-name-mapping: { request: django.http.HttpRequest, ... } """
This makes the type mapping available for all files in this directory (or sub-directories).
What do you think?
Disclaimer: For reasons I don't want to explain in detail, I am not allowed to do implement things like this. This is just an idea. I would feel proud and thankfull if someone likes it that much, that he implements it.
