option to not swallow errors

[patrickkettner]

Would it be possible to add an option to throw the error being logged? Or change the exit code so that it doesn't return a 0 and appear successful?

I would prefer to do it webpack way if possible.

For example to fail a compilation, you would do

compilation.push(error)

which causes the compilation to fail. I am not sure if something like this exists for compiler.
