Hi, last week, inspired by this list, I started to do a Python in Python implementation, after the Squeak model. Currently I have an object memory with out GC running. From tomorrow onwards I will continue to work on it. cya Gerald Stephan Diehl wrote:

Hello,

during the last days I got a little bit interested in smalltalk (article in c't 2/2003). Since smalltalk is already about 30 years old and shares some similarities to Python, some aspects of smalltalk might ease the effort to implement Python in Python. Here are some smalltalk faclets that makes it interesting: - Everything is an object (even classes and code blocks for example) - All actions are performed by invoking an object method (even loops) - there are only 5 keywords and only a couple of "special" characters - the smalltalk VM is implemented in smalltalk - smalltalk comes with "batteries included"

With smalltalk in mind, one could write a kind of ProtoPython that has much less overhead than the existing Python. Possible features of a ProtoPython (very incomplete): - smaller set of reserved words ("print","import",etc. shouldn't be reserved words) - no operators, '+','-',... will be methods - at least the for loop could be a method of a (to be defined) list class.

Even if this approach is absolutely ridiculous, just looking at smalltalk might give some ideas/hints how to construct a self describing language.
