HTML JSON form submission - Infer types using the type attribute

[phistuck]

<input value="5" type="number" name="foo"/> would yield a number. Example -
{
"foo": 5
}

Same for type="range" and so on.
type="checkbox" could yield a boolean (instead of 'on').
type="date" and friends can yield ISO formatted dates/timestamps.

I did want to suggest that myself. Therefore I express my support on this.
