D adds a very handy feature that allows you to check for a range of values in a single case. Is there a particular reason that the syntax "case <start>: .. case <end>:" is used instead of treating the case statement similarly to an array slice, e.g. "case <start> .. <end>:"?
For example: import std.stdio; void main() { int bob = 12; switch (bob) { // Why not "case 0 .. 9:"? case 0: .. case 9: writeln("Less than 10."); case 10: .. case 19: writeln("Less than 20."); case 20: .. case 29: writeln("Less than 30."); break; default: break; } // Output: Less than 20. Less than 30. } - Vijay
