I am learning about pick semantics now. Lets assume I wanted to print a Vector of Strings two times. Am I right in assuming that this will not work:

void PrintNames(Vector<String> names)
{
    for(int i=0; i<names.GetCount(); i++)
    {
        //print the name
    }
}

int main()
{
    Vector<String> myNames;
    //add a few Strings to myNames here...

    PrintNames(myNames);
    //myNames is not valid anymore?
    PrintNames(myNames);
}

Instead I will need to do this:

void PrintNames(Vector<String> names)
{
    for(int i=0; i<names.GetCount(); i++)
    {
        //print the name
    }
}

int main()
{
    Vector<String> myNames;
    //add a few Strings to myNames here...

    Vector<String> tempNames;
    tempNames <<= myNames;
    PrintNames(tempNames);

    tempNames <<= myNames;
    PrintNames(tempNames);
}
