RE: RegExp Flags

[Domenic Denicola]

Should this be added to test-262?

It'd be cool if test-262 took pull requests :).

It's supposed to be an early syntax error. See last sentence of 
http://www.ecma-international.org/ecma-262/5.1/#sec-7.8.5

Re: RegExp Flags

I think SM behavior is right to the spec.

According to 7.8.5,

 the error must be treated as an early error (Clause 16)


And early error should be reported before evaluation of the Program
(section 16)

 An early error is an error that can be detected and reported prior to the
 evaluation of any construct in the Program containing the error. An
 implementation must report early errors in a Program prior to the first
 evaluation of that Program.

 SM and v8 exhibit different behavior when evaluating the following:

 false ? /abc/ii : 0;

 In v8, no syntax error is thrown, presumably because regular expression
 flags are only validated when a RegExp object is created.  In SM, a syntax
 error is thrown because flag validation is performed by the scanner.

 The current spec seems to lean toward the v8 interpretation.  Thoughts?
