Better extension handling?

[beckend]

I have a loader which loads normal css(non local css) with extensions with accepts ".styl".
Then I have a loader which does the same but with local css ".l.styl"

I have tried extensions: [ '.l.styl', 'l.styl' ] but did not work correctly.

There is a ignore function property, but how about an include property for the plugin?

I see, I need to check it first to tell you more. And I think it's possible to add include property.

btw, do you use any preprocessCss function?

[beckend]

Sorry for the delay, missed the question, yes I use your stylus preprocessCss in README.

Another example benefiting an include option would be this react component:

I would include only the correct regex to use local css, and the rest needs to be untouched, since they are supposed to load "normal" css files on the client side.
