Type inference for exact strings #16276
Description
TypeScript Version: 2.2.2
Code
interface Css {
position: 'absolute' | 'relative';
}
function style(rules: Css) { }
const rules = { position: 'absolute' };
style(rules);
style({ position: 'absolute' });Expected behavior:
There should be no type issues.
Actual behavior:
style(rules) yields
Argument of type '{ position: string; }' is not assignable to parameter of type 'Css'
Types of property 'position' are incompatible
Using style({position: 'absolute'}) works fine.

#16360 just now seemed a bit similar (about tuples instead of objects).
