I don't understand that, either. I suppose this works differently in
different languages, though:
return i++;
return (i++);
I tried in C and Java and got the same result (both return the original
value of i), though I would have expected something different. Not sure
what, though.
What I also don't understand is why userPrincipal is used directly
instead of this.getUserPrincipal, which would allow some measure of
extensibility of the class.
Oh, well.
