I remember there being talk of eventually being able to call Julia from within Python. I've also been quite happy using Numba as an alternative to Cython for some things when I need speed. It's a lot more light-weight with less boilerplate, although still a little rough around the edges.

I don't know about calling Julia from within Python, but you can call python from within Julia. This makes it very easy to wrap and use python libraries for things which Julia doesn't have good support for yet.

Would be awkward to run django from inside julia though...

This already exists as a prototype as part of IJulia, see Leah Hanson's awesome blog post about it here: http://blog.leahhanson.us/julia-calling-python-calling-julia...

The collaboration between the scientific Python and Julia communities in recent months has been awesome to watch.
