This is like the idea of storing the code in a richer file format rather than just text. It would be up to the editor to format it and present it appropriately. This would also allow for code comments, pre-post checks, assertions, and other metadata to be embedded into the code without having to be typed in some meta language or language extensions in the plain text.<p>I would like to experiment with something like that but given how much existing plain text code there is I don&#x27;t see this happening any time soon.
