It's fantastic. I don't believe any other programming language can do this in real time (mix C++ and some other language in fairly arbitrary ways). The main downside is that the initial compilation of C++ (which happens at runtime in Julia) has to initialise the C++ (jit) compiler and run it, which is quite slow. For mathematics this isn't such a huge issue because if you have long running code you tend to not care too much about a compilation phase. But for other real time projects it would be useless. > There's not much documentation about it though, so I was wondering if you > know about the following: > > - does it support templates? > No, I don't know, sorry.

But my understanding is it will be an interactive C++ interpreter. It's probably best to ask the people writing it, since I don't know a lot about that side of the Cxx project.
