Perl 5 is a highly capable, feature-rich programming language with over 29 years of development.
Perl 6 is a sister language, part of the Perl family, not intended as a replacement for Perl 5, but as its own thing - libraries exist to allow you to call Perl 5 code from Perl 6 programs and vice versa.
The Perl Foundation is dedicated to the advancement of the Perl programming language through open discussion, collaboration, design, and code.
