We ended the previous chapter with a warning about the
downsides of the reflection interface.
That warning applies with even more force to

High-level languages insulate programs and programmers not only from the arcane specifics of individual computer instruction sets, but from dependence on irrelevancies like where in memory a variable lives, how big a data type is, the details of structure layout, and a host of other implementation details. Because of that insulating layer, it’s possible to write programs that are safe and robust and that will run on any operating system without change.
