A modern programming language that makes developers happier.

So here is what I have found out from reading the sources in the past two days: Generally speaking it is not possible to simply create a synthetic class outside the bounds of existing class, at least there is no officially endorsed way of doing so. However there are several ways to do it, if you really need to. The first way is to obtain the `CompilerConfiguration` using the `CompilerConfigurationExtension` in order to get hold of the output directory. You can then write your own files using the `BinaryClassWriter`. This way is pretty safe and should be stable across future releases. The second method would be to use either the `AnalysisHandlerExtension` or the `CollectAdditionalSourcesExtension` to access and modify the list of source files. The list of sources is leaking and can simply be casted into a `MutableList`. While this can be pretty useful, it is not recommendable, because this will probably be fixed in the future.
