#787: MacRuby Initializers only claim a single arity

----------------------------------------+-----------------------------------
When I write an initalizer, I only register it for a single arity:
rb_objc_define_method(cQueue, "initialize", rb_queue_init, 1);
Queue.new("foo")
Unfortunately, Objective-C will apparently fall back to the default (no-
arg) initializer of the superclass, leading to an uninitalized object
being allocated if I mistakenly call:
Queue.new # no args
To work around this, I've manually added an exception-throwing
initializer:
static VALUE
rb_raise_init(VALUE self, SEL sel)
{
rb_raise(rb_eArgError, "initializer called without any
arguments");
return self;
}
rb_objc_define_method(cQueue, "initialize", rb_raise_init, 0);
Would be nice if MacRuby did this automatically, to preserve Ruby-esque
semantics.
