demandimport: support lazy loading for absolute_import Before, we didn't support lazy loading if absolute_import was in effect and a fromlist was used. This meant that "from . import X" wasn't lazy and performance could suffer as a result. With this patch, we now support lazy loading for this scenario. As part of developing this, I discovered issues when module names are defined. Since the enforced import style only allows "from X import Y" or "from .X import Y" in very few scenarios when absolute_import is enabled - scenarios where Y is not a module and thus there is nothing to lazy load - I decided to drop support for this case instead of chasing down the errors. I don't think much harm will come from this. But I'd like to take another look once all modules are using absolute_import and I can see the full extent of what is using names in absolute_import mode.

demandimport: support keyword arguments on _hgextimport __import__ supports keyword arguments since Python 2.5. This proxy should too. An upcoming patch will use this feature.

demandimport: refactor logic and add documentation demandimport doesn't currently support absolute imports (level >= 0). In preparation for this, we add some documentation and a code branch to handle the absolute_import case.
