Thank you for the reply. I tried this at the REPL, and got an error:
racket@> (require (filtered-in
(λ (name)
(string-replace name "->" "→"))
racket))
stdin::4186: filtered-in: not a require sub-form ...
racket@> (require racket/require)
racket@> (require (filtered-in
(λ (name)
(string-replace name "->" "→"))
racket))
string-replace: undefined; cannot reference undefined identifier ...
racket@> (require racket/string)
racket@> (require (filtered-in
(λ (name)
(string-replace name "->" "→"))
racket))
string-replace: undefined; cannot reference undefined identifier ...
Wonder what I am doing wrongly.
Raghu.
