// @importsNotUsedAsValue: true
// @filename: a.ts
export const enum E {
One,
Two,
}
// @filename: b.ts
import type {E} from './a';
export let v = E.One;
Expected behavior:
No error.
Actual behavior:
Type-only import causes Enum 'E' cannot be used as a value because only its type has been imported.ts(1362)
Since importing const enums at runtime is not necessary due to inlining, they should be allowed to be used with type-only import.
If I use a regular import, I get This import is never used as a value and must use 'import type' because the 'importsNotUsedAsValue' is set to 'error'.ts(1371)
