2. Is there a command such as #error or #warning in D?
I assume this is maybe #pragma (msg, "error message") static
assert(0);?
D doesn't really have any of these, but you can emulate them. You can use:
pragma(msg, "warning: message")
To emulate a warning. This will be printed during compilation. For
#error you can use:
static assert(0, "error message");
This will halt the compilation with the given message.
3. Can you use static if() {} with the {} block?
None of the examples had it. I know it's because of scope
issues... but I'd hate to have to write static if(x) 5 times in a
row for 5 variables.
Yes, you can use {} after a static-if:
static if (a) {}
else {}
Note that even though you use {} it will not introduce a new scope:
import std.stdio;
static if (true) { int a = 3; }
void main () { writeln(a); }
