It can be defined in any of syntax-case, syntactic-closures
or riaxpander, but you really, really don't want to.
Nesting hygienic macros and unhygienic macros just doesn't
work.  You can still get away with simple, top-level
unhygienic macros that don't include any code body, though,
like define-record.

sc-macro-transformer (available in syntactic-closures and
riaxpander), is a lot like CL-style macros, and works with
let-syntax.

There's no reason for this - it needs to be compiled with
csc -i, but then you should be able to load it with
case-sensitive Chicken.  I've removed that restriction in my
local copy and will check it in later.

I'll add these shortly as well.
