( #3333=superdoc: print w/replies, xml ) Need Help??

Since 5.12, use 5.012; could also introduce changes in behaviour. I'm not too fond of that

Since 5.10, actually. If there was no change in behaviour, there wouldn't be need for the features pragma at all.

$ perl -e'sub say { print "foo\n"; } say for "bar";' foo $ perl -E'sub say { print "foo\n"; } say for "bar";' bar

It was always safe to try

It's no more or less safe to try now as then. By switching use 5.008; for use 5.006;, you could get bugs that changed behaviour and compile-time errors just like you do now.

Update: Deleted a comment based on something I misread.

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



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible editor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
