your example does not use def-call-out!
the default-foreign-language is used not only in def-call-out, but also
in c-function.  do you want c-win32-function too?

if the calling convention (default-foreign-language) is so crucial,
let's make the :language argument required, even when
default-foreign-language is there.

having separate def-c-call-out, def-win32-call-out &c is "the scheme
way" (TM)  :-)

in your example, the problem could have been resolved by issuing a
default-foreign-language form in top-level

here you go! :-)

*print- is a nice gun.
yes, if you are not careful, you will hurt yourself.
This is a tradeoff between the US (2nd amendment) and Europe (only
police has guns.)
I am for the US approach -  freedom above all.

we all suffer from slow responses.
