The 'cross' pattern is not intended for direct use like that. What were you intending to achieve?
from redex.
The first of those three tests passes, which is why I expected the others to work. My intention was to define a non-terminal representing arbitrary contexts by using (cross e)
.
from redex.
Here's the code in question, for easy reference:
#lang racket/base
(require
redex/reduction-semantics)
(define-language lcL
(e t ::= () (λ (x) e) (e e))
(C ::= (cross e)))
(module+ test
(require rackunit)
(check-true
(redex-match? lcL (cross e) (term (λ (x) hole))))
(check-true
(redex-match? lcL (cross t) (term (λ (x) hole))))
(check-true
(redex-match? lcL C (term (λ (x) hole)))))
from redex.
This appears to have been fixed somewhere along the way.
