FWIW, you also sometimes see

  ```math
  -b \pm \sqrt{b^2 - 4ac} \over {2a}
  ```

So to some extent the rendering is advanced syntax highlighting. I wonder where you would draw the monospace text vs rendered line on this spectrum?

  JavaScript ; poem ; ’90s email ; OP ; latex math ; ditaa 

I guess you’d put it at the end with nothing being rendered?
