guardedHandlers

Not sure if this is a bug or I'm missing something. According to https://developer.mozilla.org/en-US/docs/SpiderMonkey/Parser_API
TryStatement is always expected to have "guardedHandlers" property.

But on this link https://bugzilla.mozilla.org/show_bug.cgi?id=742612 "guardedHandlers" is marked as optional. The latter document could be outdated though.

So, esprima always adds empty array for "guardedHandlers" should acorn do this too?

Escodegen assumes this property always present in AST.

Indeed. I've updated the code to conform to that document. But I am starting to get worried about the ad-hoc way people are making changes to it. A standard that changes randomly isn't much of a standard.

Right, would be great to have some more stability and predictability there. Thanks!
