Debugger: VarItem::fullName question

[Vladimir Prus]

Hello, 
I've a question about the code below:

    QString VarItem::fullName() const
    {
        QString itemName = getName();
        QString vPath = varPath();
        if (itemName[0] == '<')
            return vPath;

When the item name can start with '<', and what does it mean?

Thanks,
Volodya
