In Perl there are 3 loop control keywords. The two commonly used are next and last and there is a third which is rarely used called redo.
In most of the other languages the respective keywords are continue and break.
next of Perl is the same as the continue in other languages and the last if Perl is the same as the break of other languages.
redo probably does not have its counterpart.
Recently I encountered a Perl script that had some issues. e.g. Lack of use strict.
Let me show a quick refactoring of it:
Recently a number of people have contacted me with various Perl-based projects. I had the opportunity to have an email exchange with them to try to understand what they need and if I can provide the help. A few question came up and for my future reference I wrote them down.
These were almost always old projects that needed some new feature added.
