I have personally written several thousand lines GCL (the generic version of BCL used at Google) and I can say that it can be pretty frustrating.

The difficulty and complexity of defining configurations using it really depends on the system you are configuring since you are (generally) just defining a set of static fields that are packaged into a protobuf and fed into whatever system you are working with.

Outside of syntax issues, it's up to the system you are configuring to provide concise config semantics and helpful error messages
