This too fails:

void main() {
    char[5][2] cs;
    cs[].join(",");
}


This is a work-around, but I agree it's too much complex and it produces too
much garbage for the collector (all those dup):

import std.stdio, std.array, std.algorithm;
void main() {
    char[5][2] cs = 'x';
    char[] j = map!(r => r.dup)(cs[]).join(",");
    writeln(j);
}


So I agree join() should support fixed-size arrays of arrays.
