Is it possible to validate list using marshmallow?
<p>Is it possible to validate list using marshmallow?</p>

<pre><code>class SimpleListInput(Schema):
    items = fields.List(fields.String(), required=True)

# expected invalid type error
data, errors = SimpleListInput().load({'some': 'value'})

# should be ok 
data, errors = SimpleListInput().load(['some', 'value'])
</code></pre>

<p>Or it is expected to validate only objects?</p>
