Could you also check if the printer will add ; for the CallSignature?

interface a {
    (a: string) : number
}

Per Object Type Literals Grammar, only the last TypeMember of TypeMemberList can omit trailing semicolon. I suggest we add another TypeMember to the test case so that ; can not be omitted.

interface a {
    new (a: string): void
    new (a: number): void
}
