import std.stdio;
import std.concurrency;

void main()
{

void sp(int i)
{
	receive((int i)
	{
		writeln("i: ", i);
	});
}

	auto r = new Generator!int(
	{
		foreach(i; 1 .. 10)
			yield(i);
	});

	foreach(e;r)
	{
		sp.send(e); //Error: function app.main.sp (int i) is not callable using argument types ()
	}

}


What I am doing wrong? How "receive" can be named? Is it's method or what? Why it's without return type?

Sp is not in global scope but defined in main.
Therefore it does not participate in UFCS.
