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

For gawds sake why would I want to do anything that silly, replacing something readable with the use of an ill-designed and ill-named nonsense? Yieiaild? There's nothing in the dictionary that would match the way this keyword is used in Ruby. Yeah, yield as a keyword related to coroutines, fine. You yield the execution and let someone outside the subroutine decide when to continue, but that's not what it means in Ruby!

sub test (&){ my $print = shift; say "You are in the method"; $print->(1); say "You are again back to the method"; $print->(2); } test { say "You are in the block $_[0]" };

is not only more readable, but also more extensible! You are not restricted to a single "callback" and if you need to pass the subroutine reference/closure/block (I know the differences, thank you very much) somewhere else you can! Try that in Ruby!

BTW, does the |a,b| finally declare new variables in Ruby or does it still reuse the a and b if they happen to be defined? Yeah, I know, a method in Ruby should not take more than four lines ... it doesn't matter you end up having hundreds of them.

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