Under the section about twigils in S02, "$=var" is described as a "pod

they're a fossil; if they aren't, I'd expect further information about

The principle of pod variables as I recall them discussed a few years ago is that it is a way for code to programmatically access its own documentation, such as, for example code introspecting a routine could also print out the documentation for that routine, I suppose. Whatever it was, it sounded useful at the time. -- Darren Duncan
