Summary
This import hook makes export a soft keyword, so that it automatically adds to
__all__ the relevant names in the following cases:
export class ClassName ...
export def function_name ...
export identifier ... = ...
In a sense, it complements the pep_843 import hook.
Export as a soft keyword
More to come.
Warning
Do not use continuation characters. The current transformation might not handle them correctly.
Warning
A line that startswith an export statement may not contain a triple quoted string that spans multiple lines.
