This is + logically a list of objects that are searched when binding an Identifier. + When control enters an execution context, the scope chain is created and + is populated with an initial set of objects, depending on the type of + code. When control leaves the execution context, the scope chain is + destroyed. + + During execution, the scope chain of the execution context is affected + only by WithStatement. When execution enters a with block, the object + specified in the with statement is added to the front of the scope chain. + When execution leaves a with block, whether normally or via a break or + continue statement, the object is removed from the scope chain. The object + being removed will always be the first object in the scope chain. + + During execution, the syntactic production PrimaryExpression : Identifier + is evaluated using the following algorithm: + + 1. Get the next object in the scope chain. If there isn't one, go to step 5. + 2. Call the [[HasProperty]] method of Result(l), passing the Identifier as + the property. + 3. If Result(2) is true, return a value of type Reference whose base object + is Result(l) and whose property name is the Identifier. + 4. Go to step 1. + 5. Return a value of type Reference whose base object is null and whose + property name is the Identifier. + The result of binding an identifier is always a value of type Reference with + its member name component equal to the identifier string. + Author: christine@netscape.com + Date: 12 november 1997 +*/ + var SECTION = "10.1.4-7"; + var VERSION = "ECMA_1"; + startTest(); + + writeHeaderToLog( SECTION + " Scope Chain and Identifier Resolution"); + + var testcases = getTestCases(); + test(); + +function test() { + for ( tc=0; tc < testcases.length; tc++ ) { + + var MYOBJECT = new MyObject(); + var INPUT = 2; + testcases[tc].description += ( INPUT +"" ); + + with ( MYOBJECT ) { + delete( eval ); + testcases[tc].actual = eval( INPUT ); + testcases[tc].expect = INPUT; + } + + testcases[tc].passed = writeTestCaseResult( + testcases[tc].expect, + testcases[tc].actual, + testcases[tc].description +" = "+ + testcases[tc].actual ); + + testcases[tc].reason += ( testcases[tc].passed ) ?
