Hi All,
I have thought of how to do it and pretty sure
it would work, but just in case Raku have one
of those sweet utilities, does Raku have a
utility that will take an array and remove all
the duplicates and rearrange the cells back
in order?
Many thanks,

I knew there had to be something! Thank you!
My keeper: perl6.array.duplicates.unique.txt
Raku (perl6): how to remove duplicates from an array:
Use `unique` and `.=`
For example:
$ raku -e 'my @a = 1,2,3,6,7,1,2,8; @a .= unique; say @a'
[1 2 3 6 7 8]
$ raku -e 'my @a = "abc","DEF","abc","jkl",1,2,8; @a .= unique; say @a'
[abc DEF jkl 1 2 8]
$ raku -e 'my @a = "abc","DEF","abc","jkl",1; @a .= unique; say @a'
[abc DEF jkl 1]
$ raku -e 'my @a = "abc","DEF","abc","jkl",1,8,1,2,8; @a .= unique; say @a'
[abc DEF jkl 1 8 2]
