Description

       These are type-checking array objects; elements are checked against the specified type when the object is
       constructed or new elements are added.

       The first argument passed to the constructor should be a Type::Tiny type:

         use Types::Standard -all;
         my $arr = array_of Str() => qw/foo bar baz/;

       If the initial type-check fails, a coercion is attempted.

       This class consumes the following roles, which contain most of the relevant documentation:

       List::Objects::WithUtils::Role::Array

       List::Objects::WithUtils::Role::Array::WithJunctions

       List::Objects::WithUtils::Role::Array::Typed

       Also see Types::Standard, List::Objects::Types

Name

       List::Objects::WithUtils::Array::Typed - Type-checking array objects

Synopsis

         use List::Objects::WithUtils 'array_of';

         use Types::Standard -all;
         use List::Objects::Types -all;

         my $arr = array_of( Int() => 1 .. 10 );
         $arr->push('foo');    # dies, failed type check
         $arr->push(11 .. 15); # ok

         my $arr_of_arrs = array_of( ArrayObj );
         $arr_of_arrs->push([], []); # ok, coerces to ArrayObj
