( [id://3333]=superdoc: print w/replies, xml ) Need Help??
This is just a hunch, but could it be that the $i in the last example is treated as a reference at the end, so that the sub is not evaluated until in the last block. So it is evaluated to the last value of $i, the value that triggered the exit from the construction loop.

Maybe this should be fixed with scoping $i so it can't be reached by the last block?

update:This is a bit silly, but this is the way I solved it when I had the same problem ("my $o" in second last block):

my ( @ref_list, $code_ref, $i ); #pass one #for SCALAR LIST for $i (1..8) { push( @ref_list, sub { print " \$i == $i\n" } ); } print "for SCALAR LIST\n"; while ( $code_ref = pop @ref_list ) { &$code_ref; } #pass 2 #for INIT ; TEST ; INCREMENT for ( $i = 1; $i <= 8; $i++ ) { my $o; $o=$i; push( @ref_list, sub { print " \$i == $o\n" } ); } print "for (;;)\n"; while ( $code_ref = pop @ref_list ) { &$code_ref; }

Title:
Use:  <p> text here (a paragraph) </p>

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.
