Write in your preferred dialect and expect it to
take over the world. Or expect users to be
interested enough to port to their dialect
(scmutils).
(Wishful thinking.)
Avoid dialect dependencies. Use standard Scheme!
(Hairshirt approach. Two problems: lack of power, lack
of efficiency. regexp, reverse!.)
Embed dialect-conditionals in the code.
(Maintenance hell. Developing code becomes totally un-fun.)
