Works just fine (but still slower than the assemble - by a lot) - provided
that you are doing parity checking of something _small_, like a single
byte.  The table gets kind of large for a 32-bit integer.  Similarly,
population counts and leading (trailing) zero (one) counts are not the
kind of thing that you'd want to do with table look-ups.  Of course,
no HLL I know of lets you inline assembly - the best solution.  _SOME_
implementations of C, Pascal, Fortran, even BASIC allow such inlining,
but the capability is not standard (makes your code - shudder - machine
dependent).
