Where did you get that scheme from ?
If you do NOT specify PERL_LOADMOD_NOIMPORT in the flags slot,
you need to have a Nullsv to terminate the varargs list of args to 
pass to import.

e.g.

  load_module(0, package_name, Nullsv, Barsv, Nullsv); // use Foo 'Bar';

  load_module(0, package_name, Nullsv, Nullsv); // use Foo;

  load_module(PERL_LOADMOD_NOIMPORT, package_name, Nullsv); // use Foo ();

Note that all the SVs you pass will be SvREFCNT_dec()ed by time call returns.

Why not the source of perl ?

No ;-)

Documented? what is that ;-)

The source ? Perl_vload_module() in op.c is not that opaque.
