informative D8 compilation errors messages?

[Tom Machinski]

Hi,

When trying to compile a JS source file, the D8 error messages that I
get by default are obtuse:

$ d8 comb.js
Uncaught: "SyntaxError: Unexpected identifier" (empty stack)

Can I get something more informative like the following (from SpiderMonkey):

$ smjs comb.js
comb.js:2: SyntaxError: missing ) after condition:
comb.js:2: if (k == 0 or r.length < k) {
comb.js:2: .............^
