The Perl Philosophy
Remember the Perl motto: "There's more than one way to do it" (TMTOWTDI, pronounced "Tim Toady").
But also remember: "There's more than one way to do it, but sometimes consistency is not a bad thing either" (TIMTOWTDIBSCINABTE, pronounced... well, we just say "Tim Toady Bicarbonate").
Perl Community Values
- Be nice - The community is welcoming
- Be helpful - Share knowledge freely
- Be creative - Embrace different solutions
- Be pragmatic - Solve real problems
- Have fun - Enjoy programming
Final Words
The Perl community is one of the most welcoming and helpful in all of programming. Whether you're debugging a regex at 3 AM, optimizing a database query, or building your first web application, you're never alone. The resources in this appendix are your gateway to decades of collective wisdom, millions of lines of tested code, and a community that genuinely wants to see you succeed.
Perl may be over 30 years old, but it continues to evolve, adapt, and thrive because of its community. Join us. Ask questions. Share your knowledge. Build something amazing.
"The Perl community is the CPAN. The CPAN is the Perl community. Everything else is just syntax."
Welcome to Perl. Welcome home.
