```(,@',,@q) ;Alan's example

Do you all believe these?
Does it matter? RWK said he has never used a triple backquote. Neither

they be maintained? Even some double nested backquotes require enough
though that they should probably be avoided. Conciseness and
compactness does not imply clarity and robustness.
