What does "object-language" mean in
http://docs.racket-lang.org/redex/tutorial.html ?
It pops up first here:
"Once we have defined the grammar, we can ask Redex if specific terms
match the grammar. This expression checks to see if the e non-terminal
(from L) matches the object-language expression (λ (x) x)."
That term isn't in the defined language L (no type), so the match fails.
Then object-language pops up again in Exercise 1:
"Use redex-match to extract the body of the function from this
object-language program:
((λ (x) (+ x 1))
17)"
Is object-language a predefined language? Or does the exercise expect me
to use define-language to create an appropriate object-language without
types?
