Of course, we can then apply the so called "micro optimisations" to that:
buk2 => sub { local $_; 1+index $_[0], $_ or return while $_ = chop $_[1]; 1; },
Though the results of doing so can hardly be called "micro" when they result in an order of magnitude speed up over the non-optimised equivalent; 15 times faster than the next best; and 60 times faster than the original!
