I like the way you use ~ in `use lib '~/...';`. Though it doesn't work as expected. But it's nice! :D Best regards, Vadim Belman > On Oct 14, 2022, at 4:05 PM, Joseph Polanik wrote: > > On 10/14/22 3:38 PM, Elizabeth Mattijsen wrote: >>> On 14 Oct 2022, at 21:15, Joseph Polanik >>>

Problem defining factorial operator in .rakumod file

I am trying to define '!' as the factorial operator. The following works in a .raku script file:   sub postfix: ($n) is export {     when $n == 0 {return 1}     default {$n * ($n - 1)!}   } However when I tried to move this sub to a .rakumod file, it produces an error: Negation metaoperator
