The idea is that rather than directory iteration returning iterators for
all path entries, it would only return those which passed a predicate which
was driven by the pattern. For some uses, the pattern might more flexibly
be a regular expression rather than the traditional (but non-portable)
wildcard patterns provided by various operating systems.
