Fastest sort of fixed length 6 int array
...
Since these are integers and compares are fast, why not compute the rank order of each directly:
inline void sort6(int *d) {
int e[6];
memcpy(e,d,6*sizeof(int));
int o0 = (d[0]>d[1])+(d[0]>d[2])+(d[0]>d[3])+(d[0]>d[4])+(d[0]>d[5]);
int o1 = (d[1]>=d[0])+(d[1]>d[2])+(d...

echo "$MYVAR" | perl -pe 's/[a-zA-Z]/X/g and s/[0-9]/N/g'

...ensions. You can do [x.name for x of users] (spec wiki.ecmascript.org/doku.php?id=harmony:array_comprehensions) . Worth mentioning that just like using map/reduce/filter isn't very 'pythonic' the other way probably holds in JavaScript. CoffeeScript is cool with them though coffeescript.org .
