Also, if you run just this program:
#lang racket
(require redex/reduction-semantics)
(define-language lc2
(e ::= x
(λ (x) e)
(e e))
(x ::= variable-not-otherwise-mentioned)
#:binding-forms
(λ (x) e #:refers-to x))
(parameterize ([default-language lc2])
(term (substitute (x (λ (x) x)) x y)))
you get the expected output:
'(y (λ (x«0») x«0»))
