What is different between Symbol() and _Symbol - page 2

[fxsaber]

void Func( const string& ) {}

void OnStart()
{
  Func(Symbol()); // ERROR: 'Symbol' - parameter passed as reference, variable expected
  Func(_Symbol);  // OK   
}

_Symbol is a system predefined variable an Symbol() is a function that return _Symbol variable content. So, for purists, _Symbol is more efficient in compilation time and generates smaller code. But, except for that, there is no difference.

This is due to the bug of passing references of temporaries.

The code above is the answer to the question in the thread title.
