Here is a paper about implementing functional data structures in Typed Racket, with some benchmarks:

What is also interesting that there is a Python language implementation in Racket[1], similar as the Racket VM can run Algol 60 code [2]. That means Racket Code can call into Python code. According to the documentation, one can even call into Python2 C extension modules[3] (I haven't tried that).
