I just wrote my first bit of Julia this weekend. I'm impressed - it's clearly been designed for technical/numeric computing with modern language features baked-in. The type system and macros are some significantly distinguishing characteristics as compared to Python. The Unitful.jl package illustrates how these can be used to powerful effect. Multiple dispatch is another such characteristic. Having benefited from static type systems in other software projects, I would never again want to write significant technical code without a first-class type system supporting declarative type constraints.

If I could never write Matlab again and instead use Julia, I'd be delighted.
