There's more than one way to do things

Update: Didn't realize that Ruby's 'yield' did not involve 'real' coroutines. The OP has since been updated.

Here's my take on accomplishing "sort of" the same thing in a couple of different ways (w/regard to argument passing) w/Coro. I know it's not the same thing, but worth comparing and contrasting and thinking about:

use Coro::State; use Coro::Channel; { my $new; my $test = sub { my ($m, $f) = @_; print "In method\n"; $f->(1); $new->transfer($m); print "In method again\n"; $f->(2); $new->cancel(); $new->transfer($m); }; my $main = Coro::State->new(); my $f = sub { print "In block: $_[0]\n" }; $new = Coro::State->new($test, $main, $f); while ( !$new->is_zombie() ) { $main->transfer($new); } print "Done!\n"; } { my $new; my $test = sub { my ($m, $q) = @_; print "In method\n"; $q->put(1); $new->transfer($m); print "In method again\n"; $q->put(2); $new->cancel(); $new->transfer($m); }; my $main = Coro::State->new(); my $ch = Coro::Channel->new(); $new = Coro::State->new($test, $main, $ch); while ( !$new->is_zombie() ) { $main->transfer($new); my $got = $ch->get(); print "Inblock: $got\n"; } print "Done!\n";

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.
