示例1: constructorErrorCheck
//
// Make sure there is enough data provided to the constructor to build
// something of the type of the constructor. Also returns the type of
// the constructor.
//
// Returns true if there was an error in construction.
//

// arguments. 'full' will go to true when enough args have been seen. If we loop
// again, there is an extra argument, so 'overfull' will become true.
