( [id://1233718]=superdoc: print w/replies, xml ) Need Help??

Welcome to the Illuminations!

Here you will find questions (from the Seekers of Perl Wisdom section) which have been esteemed by our venerable monks to be exceptional.

These questions are organized with categories (tags, keywords).

These exceptional questions will likewise have one or more replies which have been deemed best.

When you're viewing the SoPW section, or the threaded view of a question, each exceptional question and its best replies are indicated with a nice golden star: ⭐

The users empowered to designate questions and answers as "exceptional" are the Q&A Editors group.

For further information, see the FAQ How are the Illuminations maintained?
