to advanced perl modules, namely asynchronous interruptions (think \"UNIX
signals\", which are very similar).

Sometimes, modules wish to run code asynchronously (in another thread,
or from a signal handler), and then signal the perl interpreter on
certain events.  One common way is to write some data to a pipe and use
an event handling toolkit to watch for I/O events.  Another way is to
send a signal.  Those methods are slow, and in the case of a pipe, also
not asynchronous - it won't interrupt a running perl interpreter.

This module implements asynchronous notifications that enable you to
signal running perl code from another thread, asynchronously, and
sometimes even without using a single syscall.")

eval is not without its issues however - it's difficult to control the scope
it's used in (which determines which variables are in scope inside the eval),
and it's easy to miss compilation errors, since eval catches them and sticks
them in $@@ instead.  This module attempts to solve these problems.  It
provides an eval_closure function, which evals a string in a clean
environment, other than a fixed list of specified variables.  Compilation
errors are rethrown automatically.")

@code{Log::Any} has a very tiny footprint and no dependencies beyond Perl
itself, which makes it appropriate for even small CPAN modules to use.  It
defaults to @code{null} logging activity, so a module can safely log without
worrying about whether the application has chosen (or will ever choose) a

coerce values to that type.")

@code{File::Finder} object has no steps.  Each step method clones the previous
object's options and steps, and then adds the new step, returning the new
object.  In this manner, an object can be grown, step by step, by chaining
method calls.  Furthermore, a partial sequence can be created and held, and

Path::Iterator::Rule object is a collection of rules (match criteria) with
methods to add additional criteria.  Options that control directory traversal
are given as arguments to the method that generates an iterator.

A summary of features for comparison to other file finding modules:

@itemize
@item provides many helper methods for specifying rules
@item offers (lazy) iterator and flattened list interfaces
@item custom rules implemented with callbacks
@item breadth-first (default) or pre- or post-order depth-first searching
@item follows symlinks (by default, but can be disabled)
@item directories visited only once (no infinite loop; can be disabled)
@item doesn't chdir during operation
@item provides an API for extensions
@end itemize

As a convenience, the PIR module is an empty subclass of this one that is less
arduous to type for one-liners.")
