Currently, according to the docs for return(), "If called from the global scope, then execution of the current script file is ended. If the current script file was include()ed or require()ed, then control is passed back to the calling file." However, there does not seem to be a way to pass control back to the calling file from within a function. If this is by design for some reason, maybe it should be noted. Otherwise, either return should be modified some how to support this functionality (doubtful) or some other function should be provided to give this capability.
