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

what are tey, and how are they used? (In particular, I'm wondering if
they're a fossil; if they aren't, I'd expect further information about
them to be in S26.)
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
To further clarify, I put this exact question to Larry, and he
basically said that the clarification of POD variables will happen as Damian
continues work on S26-Documentation.
