Subject: Re: Operator overloading

Hi,

I'm pretty new to Ruby, so someone may step in quickly to correct me.  But
my understanding is that, for any of the standard dyadic operators (+, -,
etc.) the shorthand

j += 1

is expanded before evaluation to:

j = j + 1

I've experimented with a couple of overloads of the '+' operator, and I
always got exactly what I expected from '+=' for free...Principle of Least
Surprise, indeed :-)
