Forking #592 to it's separate issue:

Standard uses 'no-duplicate-imports' rule which is triggered if there are two or more import statements from the same module.

It seems that this rule is also triggered for import type Flow statements, e.g. this results in an error:

import { foo } from 'someModule';
import type { Bar } from 'someModule';

There is no other way to combine these two statements into one import statement as flow want's to distinguish type and value imports.

I would really like this issue to be resolved to be able to use standard style with flow typed project.
