Nested Hash / Default value is not stored

[antulik]

Seems like default value is returned but not stored.

Not sure if it makes sense to have that feature in Hashie, but it would be useful for creation of nested hashes.

> h = Hashie::Mash.new nil, {}
=> {}
> h.a['b'] = 1
=> 1
> h.inspect
=> "#<Hashie::Mash>"

I think this could be useful, indeed.

This is a way to get nested hash

> nested_hash = Hash.new { |hash, key| hash[key] = Hash.new(&hash.default_proc) }
=> {}
> nested_hash[:x][:y][:z] = :xyz
=> :xyz
> nested_hash 
=> {:x=>{:y=>{:z=>:xyz}}}

but this does not work for Hashie

h = Hashie::Mash.new { |mash, key| mash[key] = mash.class.new(&mash.default_proc) }
=> {}
> h[:x][:y][:z] = :xyz
=> :xyz
> h
=> {"x"=>{}}

Seems like this might be a duplicate of #60. I agree that it's useful and I think implementing this would also handle the other case!

@michaelherold @dblock the last case reported by @antulik is actually a bug

@brauliobo Want to take a stab at fixing it? At least write a spec?
