Returned Enum value has its type needlessly widened #20254
Description
TypeScript Version: 2.7.0-dev.20171124
Code
enum Item { potato = "potato", cucumber = "cucumber" } // inferred type is `() => Item` const getPotato1 = () => Item.potato; // type assertion works const getPotato2: () => Item.potato = () => Item.potato;Expected behavior:
Type of getPotato1 should be inferred as () => Item.potato.
Actual behavior:
Type of getPotato1 is "needlessly" widened to () => Item.
