My eval()s a code segment within a subroutine. The code it evals contains a subroutine, which I would think is completely local to the subroutine doing the eval. However the subroutine persists and I get a 'Subroutine redefined' warning whenever I call the eval more than once. See the code below. Main program is testeval.pl. It reads and evals code from testeval_code.pl 
The main program = testeval.pl
##########################################
#!/usr/bin/perl -w

# call it twice to get the 'redfined' warning
&testeval;
&testeval;

sub testeval {
    # read a replaceable code segment from a 
    # file containing the evalsub subroutne
    my $code = read_replacable_code("testeval_code.pl");
    eval $code;
    if ($@) {
        print "error eval $@\n";
    }
 
    # call the sub defined in the eval'd code
    &evalsub;
}



sub read_replacable_code {
    my $fname = shift;
    $code = '';
    if (open (FCODE, $fname)) {
        while (my $line = <FCODE>) {
            $code .= $line;
        }
        close (FCODE);
    }
    return $code;
}
