coerce is pretty nice, thank you.  It seems that when I use coerce, I
still have to define operators where MyClass is the left hand side of
the expression;
e.g., 
	4 + myObject 	# This is handled automatically by myObject's coerce
but
	myObject + 4	# fails if myObject's class doesn't define '+'.

Is this correct?
