[Pharo-project] Source in a file format ...

The Pharo File out format is currently supported by Redline Smalltalk. However, editing a class in a file in "chunk" format is not that pleasant. What would you suggest as a format for source code that is in a file? Avi Bryant of DabbleDB/Twitter fame suggested having a + (class) or - (instance) before a method pattern and just ending the method with a period. What do you think ? for example: - yourself ^ self.
