Sure.  Actually it's better to not use cer with quoted list, but
prefer using it at macro-expansion time.

I attach a sample file that create two macros `foo' and `bar', each
taking some scheme expression which are displayed and evaluated (and
the result of the evaluation is displayed too).  I use the CER feature
to get the location of the macro's arguments.

The foo macro is defined using define-macro, while `bar' use bigloo's
expander system.

Hope this helps,

Regars,
