It would be nice to find it and add to the docs.

An Array isn't a type of Str.
@ ~~ Str; # False
Array ~~ Str; # False
You can have an array that has a type constraint.
(my Str @) ~~ Array[Str]; # True
(my @ of Str) ~~ Array[Str]; # True
Or you could check that all of the values of the Array are of some type.
(my @ = ) ~~
Hi Brad,
How far should I follow the rule that I should not use a smartmatch in a
where clause?
I'm thinking of this:
> sub test1(:@array? where Str) { say 'ok' }
&test1
> test1()
Constraint type check failed in binding to parameter '@array'; expected
anonymous constraint to be met but got Array
