If we drop comments, then JSON becomes a subset of YAML, which gets us
into a more decoders. It also aligns us more closely with Python.
I have seen a case where people have been using comments to pass
metadata. I would like to drop support for such bad behavior.
I think the case is getting stronger for dropping comments entirely.
- Funny thing is, YAML was designed for human consumption as much as a
more in the LISP camp than the C camp , i.e., designed for expressive
power rather than bit-munging.
Programmers spend half their time looking at code. Ergonomics matter.
If line speed is a premium, why allow insignificant whitespace at all?
If line speed was a premium (and human consumption irrelevant), I'd be
using ASN.1 anyway; it is well established in the telecom world, and
there are tons of software and utilities that will help you with the
Think of comments as something that belong to a separate namespace. The
JSON parser should have no other business with comments than ignoring
them. If ECMAScript syntax for comments is too loose for easy parsing,
The alternative is an informal standard for comment properties that in
effect turns me into a carbon-based compiler and requires applications
to share a notation for comments anyway.
