Yes, I understand and acknowledge that unfortunately JSON does not officially support comments. I consider it a significant issue with the standard. I like to use JSON in preference to XML (let alone INI) for parameter files and have a considerable suite of programs that leverage it. The parameter files can be quite complex and the master templates are all annotated to provide users with the acceptable options and ranges.

So, it's unfortunate but I'll blame JSON and not Boost. I'll just write a file-to-stream reader that strips out the comments and pass the stream to read_json.

Still a "Booster" Mark.

(How much do you want to be that they add comments to the JSON standard next month?) msm ;-)

As a consumer of JSON and Boost it seems like a poor choice to drop
something that is so useful and has been supported for so long.

I understand your position, but something "just working" is not the same than something being supported. I cannot find any mention of nonstandard comment support in the documentation for 1.58. All I see is a link to a Wikipedia article, which reads "JSON does not provide or allow any sort of comment syntax".
