I see.
But my argument is about interoperability between implementations, e.g.
reading with Scheme implementation A code written by Scheme implementation B.
Many Schemes only support SRFI-88 keywords (arg1: , #:suffix).

Is there any Chicken function that can write code in this way?
('display' won't help here because of strings etc.)
If not, I would suggest a new parameter pretty-print-keyword-style for
the module (chicken pretty-print).

Ciao
