keeping it backwards compatible + conditional warning similar to https://github.com/karlicoss/HPI/pull/179 follow up for https://github.com/seanbreckenridge/HPI/pull/18 for now without the __path__ hacking, will do it in bulk later too lazy to run test_import_warnings.sh on CI for now, but figured I'd commit it for the reference anyway

This is here temporarily, for backwards compatibility purposes
|
|
It should be removed in the future, and you should replace any imports
|
|
like:
|
|
from my.fbmessenger import ...
|
|
to:
|
|
from my.fbmessenger.export import ...
|
|
since that allows for easier overriding using namespace packages
|
|

# TODO ^^ later, replace the above with from my.fbmessenger.all, when we add more data sources
|
|
|
|
# For now, including this here, since importing the module
|
|
# causes .export to be imported, which requires fbmessengerexport
