It's works fine if you explicitly Boolify the expression. It shouldn't need strict Boolification, it works fine with grep.

<one two three four five>.classify( *.contains​: any('a'..'f') );
P6opaque​: no such attribute '$!reified'

<one two three four five>.classify( ?*.contains​: any('a'..'f') );
False => [two], True => [one three four five]

<one two three four five>.grep( *.contains​: any('a'..'f') );
(one three four five)
