Timon Gehr: > I think it is a bit mean to say the whole semantics is a mess,
The original C design is a mess with several traps, and successive things added in D to the switch have increased the mess, they were designed from very narrow points of view, with a lack of global vision: 1) The case x: .. case y: syntax is ugly, and it doesn't respect the semantics of the .. in D that means a range open on the right. 2) The introduction of final switches is badly designed and not complete, so the safety of the situation is not improved: http://d.puremagic.com/issues/show_bug.cgi?id=5713 3) The recent improvements (that are patches on the stupid semantics of the C switch) are buggy and need a patch: https://github.com/D-Programming-Language/dmd/pull/370 Switch is too much limited, ignoring other needs: http://d.puremagic.com/issues/show_bug.cgi?id=596 I'll never agree that the C switch is well (or even "well enough") designed. Even a simple language as Pascal gets the case-of statement better than C. > switch statements and gotos provide nice means of writing highly > efficient code that still looks somewhat structured. I'd like computed gotos in D. I have discussed with Walter often about this, but he doesn't listen much on this. > Well, yes, but that is as expected.
