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

I was I was babbling in #perl on irc.freenode.net about the perl design decision to not overload '.=' to work differently when operating on an array (pushing.) I feel this should work 'as I expect it to', and there is no reason to make this operator useless when the lhs is an array, or array ref. However, my opinions aside, Rindolf made a suggestion that should be the subject of meditation and might fit even more with the Perl ideology. ",=". It should be noted that such an operator wouldn't cause breakage with 5.10 because of its status in 5.8 -- nonexistent. It would be looked upon like //=, as sexy syntactic sugar.



Transcript as follows:

12:03 < EvanCarroll> eval: @_=[qw/foo bar baz/]; @_ .= 'bleh'; @_; 12:03 < buubot> EvanCarroll: Error: Can't modify array dereference in +concatenation (.) or string at eval line 1, at EOF 12:03 < EvanCarroll> didn't think so 12:03 < EvanCarroll> oh well back to pushing 12:03 < rindolf> EvanCarroll: maybe there should be a ,= 12:04 < rindolf> EvanCarroll: you can also try to overload an operator +. 12:04 < EvanCarroll> rindolf: wow, thats actually a good idea. 12:04 < EvanCarroll> rindolf: I won't overload it for myself; but ,= w +ould fit very elegantly into the perl arsenal of operators

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 How to display code and escape characters are good places to start.
