The ? naming convention actually comes from T, a dialect of Scheme.
The only other Schemy thing I can think of is that Dylan macros are
hygienic by default, although unhygienic references are possible when
needed.

Then Dylan distinguishes between false and the empty list, but I' not
sure if that is something that can be attributed to Scheme.

Certainly Common Lisp is the language from which Dylan inherited most
of its features.  One should not forget type annotations here, or
streams and locators.

Hehe, loop is quite a nifty macro :).
