With Syntax Like This…

…who needs enemies? I wrote this code for a GUI_ScrollBar, a derivative of GUI_Control that overrides a function, calls the base, then refreshes itself. Ignoring all of the sins of a design like this…

void GUI_ScrollBar::SetPageSize(float inPageSize)
{
GUI_Controll:SetPageSize(inPageSize);
Refresh();
}

What does this code do? It loops forver and overruns the stack. Here's a hint: two L's and one colon, not one L and two colons. Now here's the cute part…there is no entity GUI_Controll with two L's anywhere. Why does it compile? This is an exercise left to the reader, one that may make you want a drink.
