Fixes #756

few very minor nits, otherwise code looks good to me!

Could you please add the rule name to this Set here and regenerate the configs:

Thanks for doing this!

Hi @JamesHenry @a-tarasyuk
Thanks for the fix, but there is 1 more case which is not covered here.
When you need to import from old modules that use the following syntax

export = ...

You must use

import moment = require('moment'); // real life example

to import them, and the rule alerts on those, while it is not valid to use back ticks here.

Do you can care to fix that as well?

hey @regevbr - please raise a new issue instead of commenting on old PRs.
