FWIW, I switched an alias I use somewhat frequently (mostly for test code/data or for throwaway passwords) to generate UUIDs. Problem isn’t important, just that it was easy to do. Install–
~>git clone https://github.com/tadzik/rakudobrew ~/.rakudobrew
~>export PATH=~/.rakudobrew/bin:$PATH
~>rakudobrew build moar v6.c
~>rakudobrew build-panda
~>panda install UUID
Switch alias from Perl to Perl6–
~>which uuid
uuid: aliased to perl -MData::UUID -le 'print Data::UUID->new->create
+_str'
~>emacs .aliases
~>which uuid
uuid: aliased to perl6 -MUUID -e 'say ~UUID.new'
~>uuid
