Hash coercion fails for ValueObject

[changeclay]

E.g. using

Hash[String => Integer]

When I initialize, I get:

 ArgumentError:
  more than one [key => value] pair in `{String=>Integer, :writer=>:private}`

@changeclay I tried to replicate your error with this

https://gist.github.com/cored/5768920

But couldn't am I missing something?

[changeclay]

require 'virtus'

class Apple
  include Virtus::ValueObject
  attribute :metrics, Hash[String => Integer]
end

ruby virtus_test.rb
ArgumentError: more than one [key => value] pair in `{String=>Integer, :writer=>:private}`

[cored]

Thanks I will try to figure this out :-)

I'm guessing there's somewhere in the code that processes the arguments passed into #attribute that assumes the last argument is a Hash of options, when it really is the type, and then it mixes in some defaults into what it thinks are "options". Some validation code then blows up when it checks the type.
