I think it's more the #if that obfuscates the code. After long
experience with #if, I really don't like it, which is why I adamantly
resist having fine-grained conditional compilation in D.
I'm used to that. If you take out the #if, it's still wierd. That one
really ought to be a goto. It's the presence of the 'else' in particular:
case A:
if (xxx)
{
case B:
yyy;
}
else
{
zzz;
}
break;
I had to read it several times before I could make sense of it. Although
the zzz; looks like it's part of the B case, it's only part of the A case.
An oddity is that this compiles:
switch(x) {
case 1:
if (x<10)
Lcase2:
writefln("yyy");
else
writefln("zzz");
break;
}
and so does this:
switch(x) {
case 1:
if (x<10)
case 2:
writefln("yyy");
}
but this doesn't:
switch(x) {
case 1:
if (x<10)
case 2:
writefln("yyy");
else
writefln("zzz");
break;
}
