Hi all, I'm writing a Perl book and I'm on an introductory Moose chapter. I'm including the following list of types from Moose::Util::TypeConstraints:
Any Item Bool Maybe[`a] Undef Defined Value Str Num Int ClassName RoleName Ref ScalarRef[`a] ArrayRef[`a] HashRef[`a] CodeRef RegexpRef GlobRef FileHandle Object In trying to explain this, I got stuck on "Item" and "Value". I have the following note about them: A word about the types in Moose::Util::TypeConstraints. "Any" means "anything" >(duh). An "Item" is the same as "Any" and in your author's consultation with >Moose experts, there was confusion expressed as to why these were different > > >A "Value" is "anything which is defined and not a reference". But since >everything which is a "Value" is also a "Str" (String) type, it's also unclear >why >"Value" was included, except for possibly defining future types which may >apply. I really would love to have a better understanding of this so that I can omit this note :) Cheers, Ovid -- Live and work overseas - http://overseas-exile.blogspot.com/ Buy the book - http://www.oreilly.com/catalog/perlhks/ Tech blog - http://blogs.perl.org/users/ovid/ Twitter - http://twitter.com/OvidPerl/
