Well, to put it bluntly, it doesn't work because you just made that
interface up. If you read the ConfigLoader synopsis at:

you'll see that the interface expects file => filename, ie a scalar NOT
an arrayref.

However, I've initiated a discussion on the catalyst-dev list about
whether this is a reasonable change to make to the interface, ie for it
to accept either a scalar or an arrayref of scalars. If the dev team
like the idea I'll make up a patch to ConfigLoader.

I'd point out at this point that anything you can do with multiple
config files, you could do with a single one -- what is your rationale
for needing multiple ones? Do you store each class's configuration
separately? I can sort of see the logic in doing that. Please mail the
list back and explain what you're doing with the multiple files, so we
can understand the use case better and see if there's a better way to do
what you need. At the very least it'll help me to make up a patch to get
the behaviour you want.

In summary, then:
1) the interface doesn't work like you think it does...for now anyway
2) you can get around it by rolling your multiple files into a single
3) just making up an interface doesn't magically cause it to exist
