When you look at the SV, my choice would be to take the float representation
over the string representation: a float is more special.

YAML and JSON are typical examples of "let's make it simpler" (silenty
to be extended with "to shoot in your own foot")  That's one of the
few justifications of XML: it is as complex as you can think ;-)

I think strict interfaces are the most important base for stable
programming.  Why do people pick a sloppy interface format (JSON), and
then a strict programming language (Java)?  Better use string interaces
(XML) and sloppy languages (Perl)  ;-b

I don't know.  Probably depends on the JSON library used.  As parser, I
would implemented some smartness if untyped information gets read for
my strongly typed language.

If you feel that JSON should produce typed info, you may ask the authors
of those implementations to solve that.
