Why doesn't (format #t ...) work now? It used to work.

Hello,
I don't know whether format ever worked differently before in CHICKEN, but
at the moment, the situation is as follows:
* The extras library unit contains a series of printf functions and an
alias for sprintf, named format. The signature for this function
corresponds to what is specified in SRFI-28 [1]:
(format format-string [obj ...]) -> string
Also the available selection of format control sequences in the
format-string is very limited, just like the SRFI-28 says.
* There are two eggs for CHICKEN which provide more sophisticated format
procedures compatible to the Common Lisp function: format and
format-modular
* format-modular is the more modern and -- as the name says -- modular and
extensible implementation of format.
* You can install both eggs in the usual way and they come with
documentation of what they can do.
cu,
Thomas
