Sweet, that's *exactly* what I was looking for.

Yeah, I was actually passing by reference in my actual code, just forgot 
it in the e-mail message (I didn't copy & paste as I was writing the 
e-mail on one machine and coding on another).

Nitpicker. =8-p  (again, this was a case of not syntax checking code 
written for an e-mail before sending).  Next time I'll write:

// Foo->privVec is empty vector
SomeClass * Foo = new SomeClass();

// Bar->privVec is copy of someVec
SomeClass * Bar = new SomeClass(someVec);

=;->

At any rate, thanks for the tips....
