Hello, following code:

import std.algorithm : joiner;
string joined = joiner(["hello", "world"], " ");

Results in:

Error: cannot implicitly convert expression (joiner(...)) of type Result to string

Any idea how to make this work ?

joiner returns a range object, not an array. To get an array out of it, do this:

	import std.array : array;
	import std.algorithm : joiner;
	string joined = joiner(["hello", "world"], " ").array;

Ha!

std.conv.to should be used instead:

    import std.conv : to;
    string joined = joiner(["hello", "world"], " ").to!string;
