This would be sufficient:
BEGIN { if( eval "use fakemodule; 1;") { print STDERR "Loaded fakemodule"; } else { print STDERR "Couldn't load fakemodule."; } }
Don't put BEGIN blocks inside a subroutine, they won't do what you want.

Don't print in the BEGIN block, it will come before the Content-type header

Calling a subroutine with the '&a' syntax has the following effects, from perlsub:

  • &NAME(LIST); # Circumvent prototypes.
  • &NAME; # Makes current @_ visible to called subroutine.
In your code you used the &a; form, which would make the current @_ visible to the called subroutine. For example:
first(1,2,3); sub first { &second; } sub second { print for @_; } # Output is 123
Although it isn't relevant for this particular case it is still good to be aware of the prototype circumvention behaviour. Here is an example:
use strict; use warnings; use Data::Dumper; sub pro(\@) { print Dumper \@_; } my @list = (1,2,3); pro(@list); &pro(@list);
Output:
$VAR1 = [ [ 1, 2, 3 ] ]; $VAR1 = [ 1, 2, 3 ];

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