Hello fellow monks,
after working through Moose Best Practices and various discussions, I decided to use build instead of default for my attributes. So far so good.
Now I have a role with lazy attributes that I apply at runtime with Moose::Util qw(apply_all_roles). This also works fine. With one exception. I get the message "You cannot have a lazy attribute (myattr) without specifying a default value for it". Calling the _build function from default works.
From Perl common sense I would say, the object is already built before the Role is applied. So you have to use default values for initialization. And so I do something like:
has 'myattr' => (
is => 'ro',
isa => 'Int',
lazy => 1,
default => \&_build_myattr,
# build => '_build_myattr',
Did I miss something?
What are best practises in my case?
Thank you for your thoughts
Update: see comment below, it's a typo. It is a "builder" instead of "build"
