Why is that useful ?

Data serialization. A string may serialize differently than an integer:

{
    "foo":1,
    "bar":"2",
}

In the case of that little JSON blurb, a well behaved JSON emitter would take {foo => 1, bar => "2"} and emit JSON with two key/value pairs, one of which has an integer value, and the other of which has a string that contains the character '2'

Why that matters is the subject of many hard to find little bugs
