Makes sense, but you cannot do this neither in C++ nor C# aswell. I guess that it is this way because semantically "cases" are not statement blocks, but just labels. BTW: bug reports and enhancements requests are less likely to be forgotten when added to the bug tracking system: https://issues.dlang.org/ (component visuald).

case statements are blocks. They might not be represented as such but they are semantically the same as blocks. The representation is irrelevant. Since, in D, every case must end with a break or return or throw, it means that the next case terminates the block automatically. So, all that needs to be done, if it is possible is to collapse everything up to the next case statement or terminal }. One could make it general for labels so one could collapse any label statement. Simply terminate up to the next label and or }.

I wasn't arguing against this, filed an enhancement request: https://issues.dlang.org/show_bug.cgi?id=19351

If the "case" deserve folding maybe just add a scope "{}" ? In my opinion case statements are often just a one liner, followed bu break and don't deserve folding.

Yeah, that might be a solution. It think avoiding having to do these types of "hacks" though are important because having to add superfluous stuff to code just to get a desired debugging experience is not good practice. It dirties up the source code adding junk that is not necessary.
