New issue 1908 by erights: Enhance stack trace for nested eval info
available on both v8 and FF30
http://code.google.com/p/google-caja/issues/detail?id=1908
From: https://mail.mozilla.org/pipermail/es-discuss/2014-March/036797.html
Cool. I will fix the debug.js adaptor
a) to fix the bug Boris reported,
b) to map the FF nested format to the v8 nested format, and
c) to preserve this information from the v8 API so that it appears
correctly on v8 as well.
This will require extending the Causeway stack trace format (an encoding of
stack trace info into JSON), which looks like it should be straightforward.
Thanks!
Once extended in this way, would it be useful to standardize the Causeway
stack trace representation, so others can avoid trying to parse the stack
trace strings with regexps?

I wasn't aware that v8 does that. Is this format documented anywhere?

I'm unclear on what the problem is with nested evals -- you get
essentially the same information from v8:
js> try { eval("eval('FAIL')"); } catch (x) { console.log(x.stack); }
ReferenceError: FAIL is not defined
at eval (eval at <anonymous> (eval at <anonymous> (repl:1:7)),
<anonymous>:1:1)
at eval (eval at <anonymous> (repl:1:7), <anonymous>:1:1)
