It's code I copied from a book.. '<=' is in Module as a 'Hierarchy Query - One 
module is considered greater than another if it is included in (or is the 
parent of class of) the other module'. Page 344 of my copy of 'Programming 
Ruby'. Sounds like it's gone now..

Good! - it looks like you're finding your way around the code ok. This ruby 
stuff is just so readable :-)

You can't declare a slot like SLOT('foobar(int myarg)') at the moment, it 
needs some code like the C++ method 'normalizeSignalSlot' that the Qt runtime 
uses to tidy up what was passed in to the declarations.
