Abstract: A compiler may receive source code including two user source code blocks, each capable of throwing an exception. The received source code may be associated with a policy that discards a pending exception when a subsequent exception occurs. The compiler may transform the source code such that it allows for a propagation policy that supports multiple exceptions. The transformed source code may be executed in an execution environment. Upon execution of the transformed code, a pending exception may be propagated out and a later-in-time exception may be stored.

Abstract: A system and method of creating an application for a mobile device platform includes determining multiple desired functions, which includes determining a desired function for each of the multiple desired functions, selecting one of a first group of functional modules, each one of the first group of functional modules provides the desired function. The multiple desired functions are then compiled.
