But I thought ModuleGetter seemed too Java-like. Could hide the class behind a getmodule function though.

The point is to provide a useful mnemonic for why you would use this context manager, and the reason is because the body of the with statement is going to initialize the contents, and you want to unwind things appropriately if that fails.

initializing_module is probably a better name than initialized_module, though (since it isn't initialized yet on entry - instead, that's what should be the case by the end of the statement)

Cheers, Nick.
