* Testcase for RegExp leniency in GitHub issue #39.
|
|
*
|
|
* Duktape 0.12.0 (and probably 1.0) doesn't pass this test, because the
|
|
* RegExp parser has no leniency for regexps outside the E5 syntax.

/* Here the '\1' escape inside a character class is invalid in E5:
|
|
* E5 Section 15.10.2.11 step 3, then E5 Section 15.10.2.19 step 2.
|
|
* V8 accepts this.
|
|
*
|
|
* Not sure what the semantics are: '\1' might be interpreted as a
|
|
* backreference. It might also be interpreted as a literal '1'
|
|
* (this doesn't seem to be the case when testing manually).
