tests/cases/compiler/arrayCast.ts(3,23): error TS2352: Conversion of type '{ foo: string; }[]' to type '{ id: number; }[]' may be a mistake because neither type sufficiently overlaps with the other. If this was intentional, convert the expression to 'unknown' first.
Type '{ foo: string; }' is not comparable to type '{ id: number; }'.
Object literal may only specify known properties, and 'foo' does not exist in type '{ id: number; }'.
==== tests/cases/compiler/arrayCast.ts (1 errors) ====
// Should fail. Even though the array is contextually typed with { id: number }[], it still
// has type { foo: string }[], which is not assignable to { id: number }[].
<{ id: number; }[]>[{ foo: "s" }];
