Additionally, what's the best way to handle nested #ifdef's? Those

global #ifdef's are turned to version blocks but versions blocks
cannot be used inside classes, stucts, functions, etc.
`static if` and `version()` can be nested, and both work just fine
inside classes, structs, functions, etc.:
module app;
version = withPrint;
struct A {
version(withPrint) {
class B {
static if(size_t.sizeof == 4) {
static void print() {
import std.stdio : writeln;
version(unittest) {
writeln("Hello, 32-bit world of unit tests!");
} else {
writeln("Hello, 32-bit world!");
}
}
} else {
static void print() {
import std.stdio : writeln;
version(unittest) {
writeln("Hello, presumably 64-bit world of unit tests!");
} else {
writeln("Hello, presumably 64-bit world!");
}
}
}
}
}
}
void main() {
A.B.print();
}
Not sure what I was doing wrong earlier. Works perfectly fine now. Glad
I asked because I usually just get frustrated and put it aside and
usually never return to it. Thanks for the assist.
