i have classified it as a bug fix, since due to the wrapping it can break assumptions about the loaded class loader, so implementing this method at least doesnt break the assumption that ``findFile()`` is available.

actually i think we should also introduced a loader interface to reduce the duct typing

:-1: for the interface:

- it would make the use of the autoloader more difficult (you would have to require the interface before requiring the loader)
- it would forbid using these wrappers with the composer ClassLoader

mh, i think all autoloaders should follow a common interface, maybe its worth to think about a PSR?

ah I see

@digitalkaoz Such an interface would have to be in PHP itself, otherwise, you would have to require it first each time (as it cannot be autoloaded before registering the autoloader). And an autoloader in PHP is just a callable.

Yes @stof, i know, but it would be nice if all autoloaders follows a common pattern , call it a convention ;)
