I think in this discussion there are two main sides: Some people want to write D code right now, so they don't want to fight too much with problems caused by const. And they like "freedom". Often this side is also associated with the "worse is better" language design philosophy. They other camp reads the texts written by the creator of the Eiffel language, that explain what Contracts are and what they are meant to. For them a precondition or an invariant should never modify the state of the struct/class. And the language should enforce this, to avoid bugs. They accept less a bit less convenience for stronger guarantees and "cleaner" code. Mathematics-oriented people are often on this side. D language has introduced const/invariant, but it's so strong that sometimes you don't want or your can't use it. So sometimes D programmers don't want to eat their own dog food. I generally prefer a more "clean" style of coding, because from experience I have seen that the amount of time wasted making a fussy type system happy, is often paid later in less bugs, that otherwise waste far more of my time. But in the end I sympathize with both camps, for different reasons. Both are partially right. In the end a static analysis tool can just enforce all invariants to be tagged with "const", so the end result is not too much different. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
