The declare marks srfi-13 as being a used unit and registers
this internally to the compiler. Unfortunately, require-extension
(aka "use") takes that as a hint that srfi-13 is already available
(this is to make things like "(require-extension srfi-0)" work,
for example: srfi-0 is a builtin feature). One could say
"require-extension" is trying to be a bit too clever...
