Hi,
Try this:
(use-modules (language tree-il) (ice-9 match))
(define foo (parse-tree-il '(let-values (apply (lambda () (lambda-case ((()
#f #f #f () ()) (apply (primitive values) (const 1) (const 2)))))) (lambda-case
(((a b) #f #f #f () (#{a 134390}# #{b 134391}#)) (apply (primitive list)
(lexical a #{a 134390}#) (lexical b #{b 134391}#)))))))
(match foo
(($ <let-values> src exp
($ <lambda-case> src2 req #f #f #f () gensyms body #f))
#t)
(_
#f))
=> #t
(match foo
(($ <let-values> src foo ;; <- rename "exp" to "foo"
($ <lambda-case> src2 req #f #f #f () gensyms body #f))
#t)
(_
#f))
=> #f
I tried to reduce this case a bit, but didn't succeed directly, and I
need to move on. But what is the deal here?

Yes.

Oh indeed, I had run ‘hg pull’ (I think) but not ‘hg update’.
Thanks!
