Cutting and pasting for posterity... :-)


import std.stdio;
import core.runtime;

immutable string abc;

void main() {
	writeln(abc);
}

shared static this() {
	alias args = Runtime.args;
	if (args.length > 1)
		abc = args[1];
}


Fascinating.  Any chance someone would be able to add this to 
http://dlang.org/module.html as an example for people like me 
who'd have no clue otherwise?
