Body param array with user defined struct produces bad output

[Kelwing]

Describe the bug
When I specify a parameter as a slice of a custom struct in the body, it produces invalid output. The schema type is set to the name of the struct instead of 'array'.

To Reproduce
Specify a Param as follows

@Param mystruct body []MyStruct true "MyStruct"

It produces the following schema:

        schema:
          items:
            $ref: '#/definitions/main.MyStruct'
          type: MyStruct

Expected behavior
Schema should be:

        schema:
          items:
            $ref: '#/definitions/main.MyStruct'
          type: array
