        OS/Version: Windows

import std.stdio: writeln;
import std.algorithm: map;
import std.array: array;
void main() {
    char[2] two = ['a', 'b'];
    auto pieces = [1, 2].map!(x => two)();
    writeln(pieces.array());
}


It gives an acceptable output (dmd 2.060alpha):

["ab", "ab"]



But printing the lazy range itself fails:


import std.stdio: writeln;
import std.algorithm: map;
void main() {
    char[2] two = ['a', 'b'];
    auto pieces = [1, 2].map!(x => two)();
    writeln(pieces);
}
