Changes

Throughout Perl's documentation, you'll find numerous examples intended to help explain the discussed features. Please keep in mind that many of them are code fragments rather than complete programs.

Throughout Perl's documentation, you'll find numerous examples intended to help explain the discussed features. Please keep in mind that many of them are code fragments rather than complete programs.

These examples often reflect the style and preference of the author of that piece of the documentation, and may be briefer than a corresponding line of code in a real program. Except where otherwise noted, you should assume that [http://perldoc.perl.org/functions/use.html use] strict and [http://perldoc.perl.org/functions/use.html use] warnings statements appear earlier in the "program", and that any variables used have already been declared, even if those declarations have been omitted to make the example easier to read.

Except where otherwise noted, you should assume that '''[http://perldoc.perl.org/functions/use.html use] strict''' and '''[http://perldoc.perl.org/functions/use.html use] warnings''' statements appear earlier in the "program", and that any variables used have already been declared, even if those declarations have been omitted to make the example easier to read.

Do note that the examples have been written by many different authors over a period of several decades. Styles and techniques will therefore differ, although some effort has been made to not vary styles too widely in the same sections. Do not consider one style to be better than others - "There's More Than One Way To Do It" is one of Perl's mottos. After all, in your journey as a programmer, you are likely to encounter different styles.
