[LC++]Using the "return value optimization"

Suppose I have a function
void doSomething(int& i, int const& parameter);
and suppose I have a class with:
class someClassTy {
...
public:
uint operator()(int const& parameter) {
int temp;
doSomething(temp, parameter);
return temp;
}
...
}
Now the only problem with the above is that I don't think
it makes use of the "return value optimization". To get
this to work, you would need some kind of syntax that
allows an integer to be initialized using a function. Ie
something like:
return int(doSomething(***here***, parameter));
Unfortunately no such syntax exists (to my knowledge). Is
there any way around my problem?
Thanks,
Mark.
