It's for that reason that you can write my $x = 10; { my $x = $x; print $x } and get 10.

Ah. This makes the behaviour of the attribute handler make sense. Hadn't thought of that. It does mean that the documentation in attributes is an oversimplification when it says:

my ($x,@y,%z) : Bent = 1;

is equivalent to

use attributes (); my ($x,@y,%z); attributes::->import(__PACKAGE__, \$x, 'Bent'); attributes::->import(__PACKAGE__, \@y, 'Bent'); attributes::->import(__PACKAGE__, \%z, 'Bent'); ($x,@y,%z) = 1;

because things like this DWIM:

my ($x,@y,%z) : Bent = (@y);

Right then. With the attribute issue out of the way - I'm still confused why INIT can see everything. Since you can also see everything in CHECK and END blocks, which are run after compilation, I still don't understand what is going on.

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 How to display code and escape characters are good places to start.
