When the switched expression is nested within a union, exhaustive typechecking needs to know which expression to check. This change adds the possibility of specifying the expression to check: ``` @component({ selector: 'app-root', imports: [], template: ` @switch (state.mode) { @case ('show') { {{ state.menu }}; } @case ('hide') {} @default never(state); } `, changeDetection: ChangeDetectionStrategy.OnPush, }) export class App { state!: { mode: 'hide' } | { mode: 'show'; menu: number };; } ``` fixes angular#67406
