in thread Passing arrayref to Moo attributes

Actually, that code won't work especially well either. (Try calling $maze->my_array.) This is because Moo lacks Moose's native attribute traits feature. (MooX::HandlesVia might help though.)

Also, FYI, Type::Tiny should run measurably faster than MooX::Types::MooseLike::Base, especially for a compound type constraint like ArrayRef[ArrayRef[Str]]. See my benchmarks.

package Cow { use Moo; has name => (is => 'lazy', default => sub { 'Mooington' }) } say Cow->new->name

    I don't think that's a Moo/Moose-compatibility issue (I could be wrong, and if so, would like additional clarification). It would be equally problematic with Moose, wouldn't it? At least after converting it to Moose by quoting the isa component, I get:

    Cannot delegate my_array to elements because the value of maze_map is 
+not an object (got 'ARRAY(0x163b880)') at...

    ...which seems to be the same type of error produced under Moo, with a slightly different message.

    But I suppose I should be asking for clarification. Should that work under Moose?

      Under Moose you need to add traits => ["Array"] to the attribute declaration. See Moose::Meta::Attribute::Native::Trait::Array.

      With Moo you'd use handles_via => "Array" but you'd need to install MooX::HandlesVia first.

      package Cow { use Moo; has name => (is => 'lazy', default => sub { 'Mooington' }) } say Cow->new->name
