Hmm.

We added the named_file_is_missing stuff because load was being called massive numbers of times for files that weren't there, especially when trying to autoload from modules.

It looks like there was a later refactor that made this method only called when an exception was raised, so it's probably ok that this is removed - at least I can't find some reason that would indicate it's not.

These performance refactors are tough to deal with down the road - it's difficult to repeat them, therefore it's difficult to know if a later refactor will bring them back, but I think this one is ok.

So, in the end: +1

Change Autoloader's load to re-raise exceptions that happen when
trying to load files, rather than just warning.

This version still does not raise an error if the file is not found, as doing so would change the behavior of 'load' pretty significantly, but I
am ambivalent this.
