IronPython is a respectable implementation, but I prefer Boo so far. I'm
having trouble with specifics, but have the sense that it is a new
Python-like language designed for the .NET platform rather than the Python
language adapted for that platform. Python is the primary language
influence of Boo, but other languages are borrowed from as well, e.g.,
functional language constructs. I suppose one's preference would be
affected by how much one wants to exploit the .NET platform or Python
language.
