    See select, the select RBITS,WBITS,EBITS,TIMEOUT section, which shows the very line as an example. It's cleaner to use
    use Time::Hires qw{ sleep }; sleep 0.25;
    ($q=q:Sq=~/;[c](.)(.)/;chr(-||-|5+lengthSq)`"S|oS2"`map{chr |+ord }map{substrSq`S_+|`|}3E|-|`7**2-3:)=~y+S|`+$1,++print+eval$q,q,a,
