I've only skimmed the article but to me it sounds like what the author wants is essentially assembly language, where everything fits in 5 columns: label, opcode, 2 operands, comment.
It's not great for usability though :)

But, high-level language can offer a very interesting possibilities, even if it was not created for such kind of programming. For example, some time ago I made another attempt to emulate family of 65xxx. Previous versions were written in typical manner, like work of every other programmer on Earth.
A new approach, when a code was written in more regular way (see link below), like mentioned tabular-one, gave me excellent results. I was able to fully understood a program and processor logic and finally I was able to re-create a most magical command for 65xx: SBC/ADC with BCD support in very straightforward and clear way (especially for a cpu-like logic).
For example: https://github.com/aniou/morfeo/blob/a83f548e98bd310995b3c37...
There is one thing that not fits into pure, tabular-like code logic: more complicated conditionals and loops. But maybe, in future...
I designed an instruction set that is reasonably convenient to input via the gamepad controllers. Instead of typing, one selects instructions and operands from lists of options. It's surprisingly fluid to input and this makes it impossible to input invalid programs.
