Perl Best Practices -

: Write test cases using modules like Test::More before writing the actual code to verify behavior from the start.

: Use descriptive, consistent names (e.g., lowercase with underscores for variables and subroutines) and mark reference variables with a _ref suffix.

: Maintain all source code, documentation, and configuration files in a system like Git . Code Layout and Style Perl Best Practices

Modern Perl best practices emphasize high-level strategy and technical discipline to ensure code longevity:

Consistency is more important than any single style choice. Automated tools help enforce these standards: : Write test cases using modules like Test::More

: Throw exceptions using croak or die instead of returning special "failure" values like undef .

: Always include use strict; and use warnings; to catch common syntax errors and unsafe practices early. Code Layout and Style Modern Perl best practices

: Design a module's interface (API) first by "play-testing" examples of how it will be used.
