What is a quick way to print a triangle? I'm thinking without 
foreach, not like I have here.

foreach(line; iota(1, 10 + 1)) {

}

These don't work:

iota(1, 10 + 1).


string result;
iota(1, 10 + 1).

writeln(result);

Not entirely the goal I'm guessing output wise, but this works.

import std.range : repeat;
foreach(line; 1 .. 11) {

That is shorter than my foreach version, but I want one that 
doesn't use foreach in it at all.

Try this:

	auto triangle(int i) {
		import std.algorithm.iteration : map, joiner;
		import std.range : iota, repeat;
		import std.utf : byCodeUnit; // this is a hack

		              .joiner("\n".byCodeUnit);
	}
	void main() {
		import std.stdio : writeln;
		writeln(triangle(10));
	}

Unfortunately, due to some silly autodecoding issues in Phobos,
byCodeUnit is a necessary hack to make this work. I'll file a bug for
this.
