Abstract: Determining how to perform operations specified in executable code. A method may include accessing a language context. The language context is related to a consumer location in executable code. The language context specifies an operation to be performed on one or more objects. The method includes sending a message requesting information about how to perform the operation on the one or more objects. A meta-object is received. The meta-object includes or produces executable code, that when executed performs the operation on the one or more objects.

Abstract: A computer program may involve a dynamic operation, which may specify one of many types of methods based on the conditions of the invocation during runtime, such as the parameters provided to the dynamic operation. The appropriate performance of the dynamic method may be achieved by analyzing the conditions of the invocation according to an evaluation rule set, the rules comprising conditions and an action to be performed if the conditions are satisfied. The evaluation rule set may also be reconfigured upon identifying a satisfied rule to facilitate a faster evaluation of the dynamic operation during a second and subsequent invocations.

Abstract: An exemplary media implementation precipitates a device to perform actions including: determining if an instruction of a line of common intermediate language (CIL) code meets a predetermined exception-related criterion; and if so, injecting a decision point in association with the instruction of the line of CIL code, the decision point enabling a decision as to whether an exception is to be thrown with respect to the instruction. An exemplary device implementation includes: instrumented CIL code that includes a test couplet corresponding to a decision point and an associated instruction, the associated instruction capable of causing a fault; a decision runtime library that is adapted to evaluate the test couplet to selectively decide whether to throw an exception with respect to the associated instruction; and a common language runtime component that interprets the decision point so as to call the decision runtime library prior to executing the associated instruction.
