There are many things you should not do with eval and those are some of them.
What I have in a code of mine still hits on the error.
#!/usr/bin/perl
use warnings;
use strict;
print $], "\n";
{ package My::Obj;
sub new {
my $class = shift;
bless {@_}, $class
}
sub DESTROY {
#my $self = shift;
#eval { 1 } if ! $self->{finished};
}
}
my $o1 = 'My::Obj'->new(finished => 1);
undef $o1;
use Carp;
# This is what I'm doing
eval q^
my $o2 = 'My::Obj'->new;
croak "Exception! $!";
^;
if ($@) {
croak 'Caught with $@:'.$@; # change $@ to $! on this line, wow...
+ 5.014002 seems to work?
}
# Exception overlooked.
eval {
my $o2 = 'My::Obj'->new;
die "Exception!";
};
if ($@) {
warn "Caught with \$\@: $@";
}
# Exception details lost.
eval {
my $o2 = 'My::Obj'->new;
die "Exception!";
1 } or do {
warn "Caught with or: $@";
};
# Same as above.
use Try::Tiny;
try {
my $o3 = 'My::Obj'->new;
die "Exception!";
} catch {
warn "Caught with Try::Tiny: $_";
};
Output:
Caught with $@:Exception! at (eval 1) line 3
eval '
my $o2 = \'My::Obj\'->new;
croak "Exception! $!";

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).

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