This could be really helpful for students learning how to read and write code! One suggestion: the code in the live demo is pretty hard to read since it is not monospaced and indented correctly (for example, the Python code won't compile.)
Yes, our goal is to assist developers learn, and understand the code they are reading and writing.
We will be replacing that code viewer in the next day or so. Thank you for pointing that out to us, as we are head down in code preparing for release in the next couple of days.
Hope to have you as part of our early access group.
Cheers.
