Switch is really a neat form of comparison and gotos but with actual

uncomment the next line and it becomes invalid:
module test;
import tango.io.Stdout;
void main(char[][] args)
{
if (args.length > 1)
switch (args[1])
case "1": Stdout("1"); break;
//case "2": Stdout("2"); break; //uncomment and error
}
Actually that is not valid code. The first "break;" breaks the program.
yeah I forgot to remove the break as it was no longer part of the switch
statement.
Ok, why on earth would a one-case switch be useful? And that still doesn't
help me understand why allowing other statement types in that position is a
good idea.
C compatibility. It's not really a problem to D. If there is a compiler
that only accepted block statements for switch not many people would
care that it doesn't conform to C spec because no one uses it like that
anyway.
