> can I use this with a named sort sub?

Sure, but you can't use the nice syntax anymore:

sub numerically { $a <=> $b } say for sort_hash(\&numerically, %hash);
($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,

    well you don't need the braces

    say for sort_hash \&numerically, %hash ;

    and this works too

    say for sort_hash {numerically} %hash ;
