Under the section about twigils in S02, "$=var" is described as a "pod
variable".  I'm not finding any other references to pod variables;
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.)
