SYNOPSIS
DESCRIPTION
Private Variables via my()
Persistent Private Variables
Temporary Values via local()
Passing Symbol Table Entries (typeglobs)
When to Still Use local()
1. You need to give a global variable a temporary
value, especially $_, 2. You need to create a local
file or directory handle or a local function, 3. You
want to temporarily change just one element of an
array or hash

Modules: Creation, Use, and Abuse
Guidelines for Module Creation
Do similar modules already exist in some form?, Try
to design the new module to be easy to extend and
reuse, Some simple style guidelines, Select what to
export, Select a name for the module, Have you got it
right?, README and other Additional Files, A
description of the module/package/extension etc, A
copyright notice - see below, Prerequisites - what
else you may need to have, How to build it - possible
changes to Makefile.PL etc, How to install it, Recent
changes in this release, especially
incompatibilities, Changes / enhancements you plan to
make in the future, Adding a Copyright Notice, Give
the module a version/issue/release number, How to
release and distribute a module, Take care when
changing a released module
Guidelines for Converting Perl 4 Library Scripts into
Modules
There is no requirement to convert anything, Consider
the implications, Make the most of the opportunity,
The pl2pm utility will get you started, Adds the
standard Module prologue lines, Converts package
specifiers from ' to ::, Converts die(...) to
croak(...), Several other minor changes
Guidelines for Reusing Application Code
Complete applications rarely belong in the Perl
Module Library, Many applications contain some Perl
code that could be reused, Break-out the reusable
code into one or more separate module files, Take the
opportunity to reconsider and redesign the
interfaces, In some cases the 'application' can then
be reduced to a small

Using Perl to dispose of temporaries
Strategies for storing Callback Context Information
1. Ignore the problem - Allow only 1 callback, 2.
Create a sequence of callbacks - hard wired limit, 3.
Use a parameter to map to the Perl callback
