I have a parser for = python3 and will try to compile python to the guile VM. This study is an = approach to add features to python that are not in. In the end I will = add mutating objects as well so that one can mix them.

I also plan to make a = system where the property of mutability can flow in the execution path = and so that dynamically if specifically requested nothing will mutate = and only new data structure will be created someting like

(define newobj = (do-not-mutate thunk))

But that's for the future.

Have fun!

So no generics? =  Looks cool.
