I play language designer in my free time, I have like ten languages buried in folders with thousands of abandoned projects.

My recent endeavour was a language with only five constructs that would mimic mathematics in the way we program:

    = assign
    $ print
    @ loop
    ? condition ! else
    # definition/function

So print hello world would be like:

    $ 'Hello world'

Every single program in the whole universe can be easily translated to Uno: Universal Notation.

I thought developing a browser extension to allow Uno being run from the address bar for quick calculations would be an interesting project.
