Yes, that's true! An integrated sweet-expression reader would be better.
My modified implementation was a multi-language extension one. But now
things has changed, sweet-expression became SRFI-105, so we ought to
make it more seriously.

Well, I just noticed there's an item "make curly brace delimiter" on
Mark's TODO list. And I did it at the volley. 
There's no SRFI-105 at that time, so I thought an easy implementation
would be enough.
