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! $!";
