$@ might not be a true value :) or other things, see Try::Tiny and Devel::EvalError for a description of the possible issue 

eval {
  execeptionalWithoutReturnValue();
  1;
} or do {
   my $exception = $@;
   ...
};

Or 

use Try::Tiny;
try {
  execeptionalWithoutReturnValue();
} catch {
  warn "caught error: $_"; # not $@
};

Or 

use Devel::EvalError();
my $ee = Deval::EvalError->new();
$ee->ExpectOne(
    eval {
        execeptionalWithoutReturnValue();
        1;
    }
);
if( $ee->Failed() ) {    # if ( ! $ee->Succeeded() )
    ... $ee->Reason() ...;
}
