That doesn't seem to stringize the args part like in

oh yeah i missed that part.
D basically can't do that exactly, but if you pass the args as
template things directly you can do this:
---
void main(string[] args) {
int a;
int b = 34;
dbg!(a, b); // notice the !
}
void dbg(Args...)(size_t line = __LINE__) {
import std.stdio;
write("#", line, ": ");
foreach(idx, alias arg; Args) {
if(idx) write(", ");
write(arg.stringof, " = ", arg);
}
writeln();
}
---
#4: a = 0, b = 34
Or reformat the output however you want.
That's so much nicer than the C++ macro. Thanks a lot!
