+1 for jupyter notebooks

@Julian:
I have not used Jupyter notebooks myself, but read about them a few 
months ago.

My understanding is that you can open the ipynb files using the 
opensource Jupyter web app and change the code interactively using code 
editors or widgets such as sliders etc. The changes would then be 
reflected back in the interface in real-time.

I suppose it would be similar to documented examples in Go: 
https://godoc.org/fmt#Stringer (click example to expand it, then click 
play to open the code in the playground), but with much more 
interactivity and a better user experience
