If #true and #false were just alternative read syntax for #t and

That's what we have now in v5.0.1.8. From the response in

Personally, I find #true and #false visually ugly, and I also agree
with Eli's feelings on terseness. I don't think I've ever
accidentally confused #t and #f personally, so I'm not in favor of

I do wish that true and false had the same number of letters. (And
there is such a parameter. See Matthew's original message for the

1. I consider concise readability as superior to short unreadability. In this
spirit, #true and #false are an improvement. I understand that more perfect
people than myself will never conflate #t with #f, but since it happened to
Matthew, I am happy not be alone. (And that happened before I
I agree. As far as students go, I've found that my PLAI students
(juniors) adapted very fast to #t and #f from the teaching languages
and that even they accidentally try to quote true and false within the
single week I teach them with the student languages. So overall I
think that #true and #false

So overall I think that #true and #false are good there [in teaching languages]
and I don't see any problem with them being available elsewhere... just not the
default.
FWIW, I would occasionally like to spell out #true and #false in my
code.

The forms `#t', `#T', `#true', `#f', `#F', and `#false' would all be
