Here are three more categories (still working from back-to-front)

• programs and processes
  • Rename Getting data into an array from a system or exec call to: How do I store and manipulate the output from another process?
  • Why aren't my backtick calls working?
    • Rename to: Why aren't my backtick calls working on Win32?
    • Clean up the question's sample code HTML
  • halting a process before my script stops
    • Rename to How can I kill subprocesses when the main script dies?
    • Combine the two answers into one, or expand on merlyn's answer to more clearly link his response to chromatic's.
• All is well in references
• regular expressions
  • How do I remove whitespace at the beginning or end of my string? should have its answers combined into one coherent answer (and I would like to see some mention of \G as referenced in Effective Perl Programming (I loaned it to someone, so cannot give a page number))
  • How can I strip away some nested markup code in html by perl, like <SCRIPT> ? : Remove the last answer (by Anonymous Monk) (not RegExp-related)
  • Regexp: spliting words w/ periods in em has a very large number of misconceptions in the question like:
    • using the binding operator in split
    • using an array as the expression to split
    I think this whole question should just be removed.
  • Double quotes within double quotes
    • Rename to How can I find nested delimiters?
    • Remove all but btrott's answer (because his works as requested)
    • Find someplace to use little_mistress' answer about greedy vs. non-greedy in regexps (perhaps a new question: "Why does my regexp match more than I want?" or something)
    • Add a reference to the Text::Balanced module
  • How do I extract all text between two keywords like start and end?
    • Encourage chromatic to edit his answer as he wished at the time
    • Possibly reference Text::DelimMatch or any other useful module
  • Remove the duplicate answer in What can regular expressions NOT do?
  • Rename <a href="index.pl?node_id="9134"> How do I split a long string without any spaces up? to How do I split up a long string with no spaces
  • Rename <a href="index.pl?node_id="11056"> I need to get the last occurences of a list of six words in a file. to How do I get the last occurence of a word (or words) in a file?
