Description

import std.stdio;
import std.range;

void main()
{
	auto str = "石室詩士施氏，嗜獅，誓食十獅。"d;
	auto indStr = str.indexed(recurrence!"n"(0));

        //core.exception.RangeError@std.range(6177): Range violation
	writeln(indStr);
}


This code prints the string correctly, but it seems that it doesn't stop when the end of the string is reached.

石室詩士施氏，嗜獅，誓食十獅。

Also, a workaround:

import std.utf;
import std.stdio;
import std.range;

void main()
{
    auto str = "石室詩士施氏，嗜獅，誓食十獅。"d;
    auto indStr = str.indexed(iota(str.count));
    writeln(indStr);

    readln();
}
