[racket-dev] #true and #false

FWIW, I would occasionally like to spell out "#true" and "#false" in my
code. Mainly when giving a Boolean value, rather than "#f" as a
``none'' value; and in something non-cramped, like a default for a
variable, rather than each value in a matrix. But for the majority of
uses I would prefer to write "#f" in my code, and to also see that as
the printed representation most of the time.
If "#true" and "#false" were just alternative read syntax for "#t" and
"#f", and they always printed as "#t" and "#f" (except perhaps in
teaching languages), that would make me happiest.
I think it's not too bad if a new programmer types "#true" in their code
and later sees the value printed as "#t". They'll figure it out within
2 seconds the first time. (It's a lot more intuitive than how the
printing of a pair changes when its CDR is another pair or a null.)
