perlbrew manages multiple Perl installations in user space. It enables switching between versions without system access.
Installations compile Perl from source in ~/perl5/perlbrew. Each version is independent with its own modules and libraries.
Libraries provide isolated module sets for the same Perl version. This enables project-specific dependencies without conflicts.
Switch sets the default version for new shells. Use changes only the current shell. This flexibility supports development across versions.
cpanm integration simplifies module installation. It's installed once and works with all managed Perl versions.
Exec runs commands against specific versions, useful for testing compatibility or building packages.

Building Perl takes time. Disk usage accumulates with versions. Some modules need recompilation when switching. Not for system Perl replacement.

perlbrew was created by Kang-min Liu (gugod) around 2010, inspired by Ruby's rvm and rbenv. It addressed the need for multiple Perl versions in development, especially for testing CPAN module compatibility.
