I don't mean to put pressure - I just leave this here for anyone.

both of these fail with an infinite loop printing i=10 on linux fedora 30, perl 5.28.2. 10 and 15 are the min numbers to do this.

use bignum (p=>1);

for(my $i = 1;$i->blt(15);$i->binc()){
    print "i=$i\n";
    
}

for(my $i = 1;$i<=10;$i++){
    print "i=$i\n";
}

this shows to me that it is not the loop or the overloaded increment but that when p=>1 it thinks that it's adding that value divided by 10 or something 

my $i = 10;
        print "1 i=$i\n";
$i++;
        print "2 i=$i\n";
$i = $i + 1;
        print "3 i=$i\n";
$i = $i + 2;
        print "4 i=$i\n";
$i = $i + 3;
        print "5 i=$i\n";
$i = $i + 4;
        print "6 i=$i\n";
$i = $i + 5;
        print "7 i=$i\n";
$i = $i + 6 ;
        print "8 i=$i\n";
