Thanks Mariano and Cyrill for your answers. The reason for trying to
make STON lighter is to use it as a document format for interactive
notebooks. When I saved the notebooks nodes from the graphical interface
their content become Text instead of strings and it generated a lot of
format information with #runs, TextColor, and other information that was
not necessary for the notebook and made the format heavy. I had problems
trying to detect were the conversion from String to Text was taking
place, so I added an extra message before serializing the notebook in
STON that takes any node content and convert it from Text to String.
After that I ended with notebooks that were 100 to 200 times smaller as
was properly reported with the amazing commit message [1] :-)

The next step is to made STON DVCS friendly by removing long lines [2]

Not sure which is the reason of making it lighter, but you may also
want to use a compressing stream so that the resulting stream is much
smaller.

HI,
There is a method in the class side of Object to override. This method
return all the instVar name that need to be serialized. You can
override it to store only the text.
For example:
Text class >>stonAllInstVarNames
"Override to encode my instances using a custom set of instance
variables or to define their order."
^ self allInstVarNames \ #runs
