( [id://3333] : superdoc . print w/replies, xml ) Need Help??

Ah sorry, I stand corrected. I was reading your code as: for( do { tie my @x, "MyClass", "first", "second"; @x } ) {

So indeed: for( @{ tie my @x, "MyClass", "first", "second"; \@x } ) {

will make for() iterate over a tied array. In fact,

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 { return scalar @data } package main; sub wrapper { tie my @x, "MyClass", @_; \@x; } for( @{wrapper("first", "second")} ) { print "In loop = "; print "$_\n"; }

also works. So it's quite close to what I want, yay. Any improvement is welcome :-)

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.
