+TargetMilestone: ---
+Summary: IDENTIFIER lexical rule, incomplete.
+At mcs/class/Microsoft.JScript/Microsoft.JScript/jscript-lexer-parser.g,
+there's a rule named IDENTIFIER, currently it's defined with a simple set
+of rules, but it's not the one that's on EcmaScript-262 spec.
+Take a look to it and fix it (section 7.6 from Ecma-262 spec, page 14).
+Basically, find out the ranges for  Lu, Ll, Lt, Lm, Lo, Nl, Mn, Mc, Nd, Pc,
+on the Unicode spec.
+To test it, you will need to compile the parser and lexer, in order to
+achive that, you need the antlr.runtime.dll. I've put one, at:
+In order to recreate the parser and lexer, execute:
+1) java -cp /classpath/to/antlr antlr.Tool jscript-lexer-parser.g
+I'm assuming you already have antlr-2.7.2 on your system, if you don't have
+it, just download it from: http://antlr.org/. Unpack it. And you classpath
+for it, it's PREFIX/antlr-2.7.2
+2) Go to mcs/class/Microsoft.JScript, execute 'make'. You'll get the new
+Microsoft.JScript.dll at mcs/class/lib
+3) Copy mcs/class/lib/Microsoft.JScript.dll to
+mcs/class/Microsoft.JScript/Microsoft.JScript or /usr/local/lib
+4) Go to mcs/class/Microsoft.JScript/Microsoft.JScript
+5) mcs -r Microsoft.JScript.dll -o mjs.exe driver.cs
+You have now the compiler, just execute: mono mjs.exe your_tests.js to test
+your rules.

+This got fixed with Rhino's parser port to C#, that's being used now.
