Well, to be fair, I didn't port SRP, I just used the existing Squeak
port. (Might have made a few tweaks to get it working on recent Squeak
releases.) I used SRP for early versions of Monticello2, but then
switched over to a custom serializer. There were a few reasons for
this:

- I wanted to optimize for encoding efficiency - ie. shorter byte
sequences for a given object graph
- I needed to ensure that a given object graph would always product
exactly the same byte sequence
- I wanted to be able to turn a graph of objects into a sequence of
objects as a separate operation from encoding them as bytes

I might have been able to bend SRP to my will, but I figured it would
be easier to start from scratch. Eventually, I started using this
serialization code in other projects, and separated it out into a
separate package, called Serialization&Materialization. It's very
focussed on my somewhat odd needs, though, and probably not useful for
the general case.
