Subject: Re: Calling class methods from C

From the top of my head:

rb_funcall(rb_const_get("CallTest"), rb_intern("go"), 0);

And if you're calling "global" methods, it's better to call it on
Kernel, where the methods are defined anyway:

rb_funcall(rb_mKernel, rb_intern("method_name"), args);

Hope that helps.
