tagging typed data in JSON: should we?

[rjbs]

I wrote a little Data::Printer filter for my own use, which annotates data that are clearly typed by being JSON::Typist or JSON::x::Boolean objects. So instead of:

[
  [0] "foo"
  [1] 90210
  [2] true
  [3] "bar"
]

You could get:

[
  [0] "foo" [jstr]
  [1] 90210 [jnum]
  [2] true  [jbool]
  [3] "bar"
]

Where 0 is a JSON::Typist::String string and 3 is just a plain scalar.

I find this useful in debugging problems, and @garu suggested maybe we should apply it to Web. But it will be a visible change, so I'd like to get confirmation that we want this before I write a PR.
