So I think there are multiple behaviors that are being described here and I
think there is validity in being able to potentially patch/modify
definitions when absolutely necessary, but I wonder if there's room here
for something in-between (also, I find the 'import export' or 'export
import' statements quite hard to read. Please don't combine 2 verbs in one
statement)
Here's my preference (which admittedly is partially taken from
NodeJS/Javascript):
"""
# Base examples
export x = 2
export x as y # Export a previous name under a new name (not quoted to
emphasize it must be a valid variable name, not arbitrary string)
export class MyClass:
pass
export DEFAULT = MyClass()
DEFAULT.setup_with_defaults() # exported entities named within this module
are named entities
# Exporting from other modules
from .my_submodule export * # This is just syntactic sugar similar to
"from .my_submodule import *" where in this case it's a pure forwarding
reference. Debatable on whether or not the found name are assigned to in
the current local namespace
from .my_other_submodule export ThisInterface as ThatInterface
"""
That said, I'm very new here and understand there are likely multiple
edge-cases I'm not considering. But I am a very interested stakeholder in
the result :-)
Cheers,
