[Chicken-users] mixing hygienic and low-level macros

[Reed Sheridan]

Hi,

Looking through the Chicken sources, I see that most macros are defined
twice, once with syntax-case and once with low-level macros.  Why
go through the trouble of defining them with syntax-case if they're
already defined?  Is there some pitfall to mixing the use of
define-macro and syntax-case that I'm missing (it seems to work fine
for me), and should I worry about this for my own code?
