> Alphabetical. Surely if you are trying to eye-parse some code and want to know if a particular modifier has been applied, this is the clearest and fastest approach to use.

I disagree.

First one should separate modifiers which are s/// only from standard m// modifiers (the latter (most?) can also be pre-compiled into the regex using qr// )

Than ordering by (and/or)

make sense.

For instance /a /d /l /u are perlre#Character-set-modifiers ° but are mostly listed as /dual for obvious reasons, the word "dual" is far easy to remember. (I'd even argue that /i belongs to same category but which much higher frequency)

So I'd say divide and conquer, humans can grasp sets with 5 to 7 elements far more easily, so 5 categories with at most 5 elements should fit

(... because of connectivity problems the rest of the post got lost :/ ... TL; don't want to rewrite and posting by tethering thru mobile)

so my bet at the moment is the following order by categories, respecting frequency and memorization

Categories

° not sure why the deep linking doesn't work (for me) seems like the anchor is missing.

² in 5.10 perlre only listed 7 modifiers and already did a categorization: "g and c: Unlike i, m, s and x, these two flags affect the way the regex is used"

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
