( [id://3333]=superdoc: print w/replies, xml ) Need Help??
So it got me curious, and I did a quick-and-dirty test implementation of scalar > file() and fstream() << scalar. But I get the "useless use of ... in void context" warnings.

So my tangential question: Is there a way to "export" the no warnings 'void' from inside the streaming package, rather than requiring it in ::main? It would be best if it could just turn off the warnings for the streaming objects, but leave the warnings on for non-overloaded uses of comparison and bitshift. I tried putting the no-warnings inside the overloaded functions, to try to keep the scope limited, but that's not the right place to prevent the warning. (Yes, I understand this isn't necessarily good practice, or "nice" to the external user. This is just for my own curiosity, and not something I'd put in practical 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 janitor intervention).
