- **Provide a detailed analysis of the question.**

    - [Why doesn’t the .* consume the entire string in this Perl regex?][1]

    - [How do I compare two strings in Perl?][3]

- **Asking why the question doesn't do the preferred method.**
<br> This can be difficult to get right. If you come off as mean, people will down-vote your answer, instead of up-voting it.

    - [In Perl, why do I get a “syntax error” when I try to use string eval?][q1]

- **Post an answer that does what the OP wants, but the way it should be done.**
<br> Specifically, not what the OP is asking.

- **Post multiple answers that are significantly different.**
<br> For example to the question [Regular Expression to match valid dates][mult-question], I posted three different answers.

    - [This one shows how to write it maintainably in Perl][mult-maint]
    - [I also wrote an expanded version of the answer provided in the question][mult-expand]
    - [I even wrote an answer using a Perl 6 rule][mult-new-language]
    - I might even write a [Perl 6 grammar][Perl6-grammar].
