[racket] Are there Racket structures similar to Common Lisp's?
Is there the equivalent of Common Lisp's /structure/ type in
Racket? I looked through Racket's User Guide and Reference
manuals but did not see something similar, although it's
quite possible that I saw one but did not recognize it.
Specifically, here is what I want. Consider the Common Lips
definition of a /person/ structure:
(defstruct person
name
age
waist-size
favorite-color)
Then create an instance:
(make-person :age 35
:favorite-color "blue"
:name "Bob")
The latter echos:
#S(PERSON :NAME "Bob" :AGE 35 :WAIST-SIZE NIL :FAVORITE-COLOR "blue")
Let's note that the order of fields when invoking /make-person/
need not be the same as the order in which the /person/
structure is defined.
Furthermore, since /waist-size/ was not specified at invocation,
it was assigned NIL.
