+Loads the module whose name is pointed to by the string part of name.

+Eg, "Foo::Bar" instead of "Foo/Bar.pm".  flags can be any of
+PERL_LOADMOD_DENY, PERL_LOADMOD_NOIMPORT, or PERL_LOADMOD_IMPORT_OPS
+(or 0 for no flags). ver, if specified, provides version semantics
+similar to C<use Foo::Bar VERSION>.  The optional trailing SV*
+arguments can be used to specify arguments to the module's import()
+method, similar to C<use Foo::Bar VERSION LIST>.
