#!/usr/bin/perl use strict; # For debugging: sub dump { my( $name, $ref ) = @_; require Data::Dumper; my $dumper = Data::Dumper->new( [$ref], [$name] ); $dumper->Indent(1)->Useqq(1)->Terse(1); print STDERR $dumper->Dump(); } my $foo = "Test value"; dump( foo => $foo ); # Should instead used: #&dump( foo => $foo ); # ...

produces:

abnormal program termination

Helpful, isn't it? I suspect quite a few people don't immediately see what the problem is. I also suspect that no small number of people could waste quite a bit of time trying to figure this problem out before the solution comes to them and they snack themselves in the forehead.

Adding the & or renaming the sub to debugDump or moving the sub to a module will solve the problem.

The problem is that dump is a built-in. I don't care to memorize the entire list of Perl built-ins nor to put my code at risk when new built-ins are added (rarely).

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.
