Foundation/CPException.j: _CPRaiseRangeException and _CPRaiseInvalidArgumentException called METHOD_CALL_STRING(), undefined anywhere.
Every out-of-bounds CPArray access threw an
uncatchable JS ReferenceError instead of CPRangeException/
CPInvalidArgumentException.
Fixed to call the existing _CPMethodCallString(anObject, aSelector).
Tests/Foundation/CPArrayTest.j, CPMutableArrayTest.j: the defect
was invisible because test_objectAtIndex_ and test_objectsAtIndexes_
checked only that something was thrown, not what.
Added exception-identity checks, and fixed ConcreteArray/ConcreteMutableArray's
objectAtIndex: overrides, which threw a plain string and would have
failed the new checks.
Replace the unhygienic METHOD_CALL_STRING() C pre-processor macro
in CPException.j with a standard JavaScript helper function,
_CPMethodCallString().
Add a `// MARK: - Exception Utilities` navigation landmark.
This removes a legacy text-substitution dependency, enabling
single-pass AST generation for the platform-native compilation pipeline.
As we have a tool-free bridges between many classes and JavaScript types by setting the isa property on the type, for example CPArray and Array. Using the for...in enumeration the isa property will be included in the loop if the property is enumerable (this is the default behavior). This commit set the property as not enumerable.
Also added test case for check that the isa property on classes are not enumerable using a for...in loop.
