The main difference is that the latter won't work unless you add () after getString. The lesser difference (after fixing the main difference) is that the former will construct a temporary VSpace object and use the copy-constructor to construct "value" from this temporary whereas the latter directly constructs the object. So the latter might be more efficient. "might" because the compiler might optimize away the temporary, so the result could be identical.

Because the Java "object" is in fact only a pointer to some object with neglectible costs for copying... Andre' -- André Pönitz .............................................. [EMAIL PROTECTED]
