File consisting only of imports throws error

[mwoelk]

I've tried to split my whole schema to be able to put the schema-parts and corresponding resolvers together.

I ended up with a file structure like this:

├── generated
├── resolvers
|   ├── User
|   |   ├── queries.ts
|   |   ├── mutations.ts
|   |   └── user-schema.graphql
|   ├── Post
|   |   ├── queries.ts
|   |   ├── mutations.ts
|   |   └── post-schema.graphql
|   └── index.ts
└── complete-schema.graphql

And schemas looking like this:
user-schema.graphql

# import Post from "../../generated/graphcool.graphql"

type User {
  id: ID!
  email: String!
  name: String!
  posts: [Post!]!
}

type Query {
  me: User
}
...

My main schema ended up being empty (except for the import statements):

complete-schema.graphql

# import Query.*, Mutation.* from './resolvers/Post/post-schema.graphql'
# import Query.*, Mutation.* from './resolvers/User/user-schema.graphql'

Which leads to an Syntax Error: Unexpected <EOF>.

It only works if I change the schema to:
complete-schema-working.graphql

# import Query.*, Mutation.* from './resolvers/Post/post-schema.graphql'
# import Query.*, Mutation.* from './resolvers/User/user-schema.graphql'

# We need at least one 'real' definition or things go south ;)
type Dummy {
  dummy: String!
}

It would be great if we could use files that consist only of import statements without having to add dummy-types.
