A very interesting project: building a language with a far more Lisp-like structure on top of the normal Python runtime. Compiles to the same bytecode as Python. Can be mixed with Python and also supports IPython as a shell.
With Logix, for example, the boundary between statement and expression finally falls away: in Logix everything is expressions. Lambda expressions that execute multiple commands and conditional expressions without detours through boolean expressions become possible.
There are also macros. The definition looks somewhat wild, but all the mechanisms seem to be there as they are also common in Common Lisp. So not just syntactic sugar, but real code-generating macros.
Of course everything is still alpha at the moment, but it already sounds very interesting. I'll keep watching this, it could definitely be interesting for me. Especially because I can mix it with Python.
