I recently tried to learn how em-syntax-rules work, because they seem
like a really good idea. However, even though there is a special
"cond-expand" for Chibi, the version at least as late as
2aa6dc829eea7c972b80ab740e073f3755bd8504 seems to have some
er-macro-transformer-related incompatibility.

I am not good enough in macrology to find out where the problem lies,
so I would like to ask more experienced colleagues for help.
