Sounds like the ClassLoader in Java. I think it would be a good idea. On 11/08/2009 05:24 AM, Nick Coghlan wrote:
... Anyway, the gist of the idea in the subject line is to take all of the PEP 302 data stores and make them attributes of an ImportEngine class. This would affect at least:
sys.modules sys.path sys.path_hooks sys.path_importer_cache sys.meta_path sys.dont_write_bytecode
The underlying import machinery would migrate to instance methods of the new class.
The standard import engine instance would be stored in a new sys module attribute (e.g. 'sys.import_engine'). For backwards compatibility, the existing sys attributes would remain as references to the relevant instance attributes of the standard engine.
Modules would get a new special attribute (e.g. '__import_engine__') identifying the import engine that was used to import that module. __import__ would be modified to take the new special attribute into account. ...
