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

I ran into's flakiness just yesterday after sprinkling in the following debug line:

warn "RDBO version: $Rose::DB::Object::VERSION;"

Because that caused's dubious heuristic to indicate that there was no need to require Rose::DB::Object I saw an error message along the lines of...

Can't locate object method "mk_ro_accessors" via package "Foo" at basebug.plx line 11.

The workaround:

END { no strict; warn "RDBO version: " . ${ 'Rose::DB::' . 'Object::VERSION' }; }

The $Foo::VERSION scalar doesn't have to be assigned to; its mere presence in the code as a package global gives it a stash entry and an undefined value. That's apparently enough for is a good idea, but the implementation is problematic.

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 janitor intervention).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
