I looked at the p.97 in the D Cookbook, and it calls rt_init() from C.

I was wondering, isn't it easier to put this initialization in a static 
this(), in the D module directly?

e.g. in test.d

import std.stdio, core.stdc.stdio : stderr;
extern(C) void helloC() nothrow; // a function from C

extern(C)
void helloD() nothrow {
	helloC();
	try {
		writeln("hello from D!");
	} catch(Throwable t) {
		fprintf(stderr, "writeln threw an exception.\n");
	}
}

static this(){
	rt_init();
}
