I have an upcoming project which would benefit from an embedded scripting language. I would personally rather use Python than Lua, and people writing scripts are more likely to be familiar with Python.

I also have an interest in language implementations (interpreters, garbage collectors etc.). I am therefore considering both scratching my own itch and indulging my interest - by writing a new, embeddable implementation of Python.

Like Lua, this implementation would be lightweight - so it could only support a subset of the Python language. I believe a Ruby implementation with similar goals already exists: https://github.com/mruby/mruby

However, I am aware that a new language implementation represents a large amount of work. If I am going to spend a significant amount of time on something like this, I would like the result to be useful to others as well as to myself.

Would you consider using a Python implementation designed along the lines of Lua? If so, are there any particular features which you would like it to have?
