SmallTalk-like interactive environment on base of cPython 2.7.x + wx

[Dmitry Ponyatov]

Does anybody can recomend some links on tutorials on making custom dynamic languages or objects systems on top of cPython2 ?

I want some interactive dynamic object environment with SmallTalk look&feel but with Python syntax.

Other tutorials I'm interested in are reflection, dynamic bytecode (de)compilation, using internal Python parser (for syntax highlighting for example), metacompilation (?) and making dynamic object VMs on top of cPython.
