Say you now go ahead and use EASY-HANDLE as follows:

    (defcfun foo :void (handle easy-handle))

When FOO is compiled, CFFI will instantiate an EASY-HANDLE and poke it
to determine things like the basic C type it translates. Your
definition is not adequate because it'll call CURL-EASY-INIT at this
point.

HTH,
