Yes, this proposal is basically AppleScript.

AppleScript is (relatively) easy for non-programmers to read and understand, because it is built on natural language.

Unfortunately AppleScript is a huge pain to write, because as a programming language it is still quite strict about what type of syntax it will accept. It also is fairly limited, because speccing a natural language programming vocabulary/grammar gets increasingly difficult as you start adding features.

As a result even the best AppleScript programs are not concise at all, with limited use of abstraction. Most AppleScript programs are cobbled together by copy/pasting code found on the internet, and are full of bugs.
