I've been thinking about this. The code that does this for SRC_URI is
quite complex and potentially problematic as it stands. The idea above
would entwine that with the parser and I'm not sure it can be made to
work in a way which wouldn't avoid circular dependency issues or behave
in a way which the user expects. Therefore, whilst I can see the
attraction, I'm not sure its something we'd want to do.
