The problem is, as you say, it is quite doable, as long as you have internal access to all of the code. There's no way to ensure that, for example, a function actually returns an immutable map, or actually doesn't modify a map passed to it. (And no, Collections.immutableMap doesn't.) (And then there are problems with the JVM bytecode as well - do you know you can pass 2 into a function expecting a boolean? And sometimes it'll get treated as true and sometimes as false? The JVM is "wonderful" like that.) |
