Can integrate with GUI toolkits (Tk, WxPerl)

Text output to console or files

Web content generation via CGI/templating

Network I/O for automation tasks

Procedural scripting

Module-based code reuse

Object-oriented Perl with `bless`

Event-driven programming possible via frameworks

Pipeline-style processing for text/data

Log file parsers

System monitoring scripts

Web CGI applications

Bioinformatics pipelines

Network automation scripts

Text and string manipulation first

Write programs that work and are readable

Emphasis on flexibility and multiple approaches

Leverage CPAN ecosystem for code reuse

Rapid scripting and prototyping focus

Write modular code with packages

Use CPAN modules for common functionality

Optimize regex and file I/O operations

Parallelize tasks using forks or threads if needed

Use database or caching for large datasets

Port legacy shell scripts to Perl for automation
