Is there a way to take a priori knowledge out of field definitions?

Hi, It is possible to build a system where the fields are "self defining" : - One way is to keep a dictionary of tags and descriptors, and to keep "the data" in a dictionary using the same tags as keys, with values - an oversimplified example: DefinitionDict = {1:'Quantity',2:'Price',3:'Value'}

PyPy with a smaller PVM for the full Python?

Currently PyPy is working toward compiling to C a restricted subset of Python, called RPython. Would it be possible for PyPy to "compile" the full subset of Python by also using a lot smaller version of the PVM (Python Virtual Machine) to go with the "compiled" code? So, the user would be running
