I disagree. Here is the full code and FETCH is only called once for each element within the body of the loop:

use strict; use warnings; package MyClass; use Tie::Array; our @ISA = ('Tie::Array'); our @data; # mandatory methods sub TIEARRAY { my $class = shift; bless \@data, $class; @data = @_ +; return \@data } sub FETCH { print "FETCH: "; my ($self, $index ) = @_; return $dat +a[$index] } sub FETCHSIZE { print "<FETCHSIZE> "; return scalar @data } package main; for( @{ tie my @x, "MyClass", "first", "second"; \@x } ) { print "In loop = "; print "$_\n"; }


In loop = FETCH: first In loop = FETCH: second

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).
