encoding/json: decoder won't unmarshal scientific notation into integer

[gopherbot]

by dave@lytics.io:

What steps will reproduce the problem?
If possible, include a link to a program on play.golang.org.

JSON decoding from scientific notation into an integer is not allowed by the JSON
decoder.

Here is an example:
http://play.golang.org/p/yS3YNvt8BB


What is the expected output?

When decoding the JSON value 1e+06 into an int64, I'd expect decoding to succeed.

What do you see instead?
JSON Unmarshal() returns an error: "json: cannot unmarshal number 1e+06 into Go
value of type int64"

Which compiler are you using (5g, 6g, 8g, gccgo)?

6g (I think), this is amd64, not gccgo, using vanilla binaries from the tarball from
golang.org.

Which operating system are you using?

Ubuntu 13.04

Which version are you using?  (run 'go version')

1.1.2

Please provide any additional information below.

It's not rigorously defined but I feel this should work. If the value fits, it should go
into the box.
I admit it's debatable.

Labels changed: added priority-later, removed priority-triage.

We decided against this a while back. I'll find the bug.
