  			trying to do better is more work and regex-computation-time than it's worth though.
  			- we'd like to have the "delimiter" parts of the stack effect [ (, --, and ) ] be a different (less-important or comment-like) colour to the stack effect contents
  			- we'd like if nested stack effects were treated as such rather than just appearing flat (with `inside`)
  			- we'd like if the following variable name conventions were recognised specifically:
  				special row variables = ..a b..
  				type and stack effect annotations end with a colon = ( quot: ( a: ( -- ) -- b ) -- x ), ( x: number -- )
  				word throws unconditional error = *
  				any other word-like variable name = a ? q' etc
