Hello,

Thank you for the great libs so far.

Quick question regarding the `meta` feature in Dry::Types. Can someone please let me know how to access the meta properties in the example below.

example:

```auto
class MyClass < Dry::Struct
  attribute :age, Types::Integer.meta(foo: :bar)
end

```

So in the example above I need to have access to the meta :foo prop.

Thank you in advance.  
LP

Hey!

You can get it like this:

```ruby
MyClass.schema.key(:age).meta
# => {:foo=>:bar}

```
