glob In list context, returns a (possibly empty) list of filename
expansions on the value of EXPR such as the standard Unix shell
/bin/csh would do. In scalar context, glob iterates through
such filename expansions, returning undef when the list is
exhausted.
Funny, I never noticed that behaviour before. AFAIK it's the only perl
function that behaves that way. Definitely a gotcha!
