Hello,

In our syntax-case implementation, module/ice-9/psyntax.scm, the
following license text can be found:

--8<---------------cut here---------------start------------->8---
;;; Portable implementation of syntax-case
;;; Originally extracted from Chez Scheme Version 5.9f
;;; Authors: R. Kent Dybvig, Oscar Waddell, Bob Hieb, Carl Bruggeman

--8<---------------cut here---------------end--------------->8---

Due to restricting the use to "lawful purpose", it conflicts with the
(L)GPL, as it places restrictions on running the program.

Perhaps there are alternative, clean implementations out there under a
suitable license we could use?

Haven't heard back, but this doesn't seem to be an issue, after all.
Closing.
