What are good alternatives to strict and warnings, and how do they compare?

In Perl programming, while using 'strict' and 'warnings' pragmas is a common practice to enhance code reliability, there are alternative methods and practices that can also improve code quality. Here we explore some alternatives and their comparisons.

Alternatives to 'strict' and 'warnings'

• Use of Tidy: Perl::Tidy is a tool that helps format your Perl code. Although it doesn't enforce strict variable declaration, it helps enhance readability and detects some syntax errors.
• Use of Lexical Scoping: Lexical scoping can limit the scope of variables, helping prevent unintended side effects even without 'strict'.
• Module: Devel::All: This module integrates multiple useful tools that can offer debugging and safety features similar to 'strict' and 'warnings' by catching more programming nuances.

Comparison of Alternatives

While these alternatives can provide certain benefits, none of them completely replace the need for 'strict' and 'warnings'. Here’s a brief comparison:

• Ease of Use: 'strict' and 'warnings' are easy to implement and offer immediate feedback whereas tools like Tidy require additional setup.
• Functionality: 'strict' significantly limits potential errors by enforcing variable declarations while 'warnings' helps catch runtime issues. Alternatives may not cover all aspects of error prevention.
• Readability: Using Tidy improves code aesthetics but doesn’t provide error protection, which is ultimately the primary purpose of 'strict' and 'warnings.'
