You might want to check out Julia[1] programming language. I have absolutely no idea how good or bad is it but considering the fact that it's so young -- you are still able to influence it's development (e.g. suggest better testing capabilities) if you really wanted to.
The webpage is down, so I'll take a look at it later. I'd like to see some simple examples of things as well.
It should be a one-liner to import a CSV file and do a least squares regression on different columns.
It should also be a one liner to open an image, compute it's 2d FFT, and display it.
It should also be one-liners to do numerical quadrature integration, compute the solutions to some ODEs, and maybe even backpropagation training of a neural network with just one layer.
