BrowserUK: Unpack in your above code also creates a list, which seems to be the same bottleneck. Benchmarks are in the same range.

Also tried List::Util::pairs(), which benchmarks a little faster. Maybe I can copy and inline this part of C code.

What I maybe will do now is providing different formats, AoA [2][L], AoA[L][2] and 2 bitstrings (match-index). Bitstrings should be very fast, but not so convenient to process. Perl5 does not have the functions lsb (index of lowest significant bit) and msb, which Perl6 has.
