It appears to be a long-standing bug, I couldn't find an older compiler version that it worked with (haven't tried bisecting though). I'm pretty sure it's ctfe specific. --

Uranuz from D.learn also hit this bug - in his/her case for structs:

http://forum.dlang.org/post/noq45h$lgu$1@digitalmars.com


struct A
{
    import std.algorithm: map;
    import std.array: array;
    import std.typecons: tuple;


    static immutable aaa = [
        tuple("1", "one"),
        tuple("2", "two"),
        tuple("3", "three")
    ];

    static immutable bbb = aaa.map!( a => a[0] ).array;

}

void main()
{
    A a = A();
}

//---------

Compilation output: /opt/compilers/dmd2/include/std/algorithm/iteration.d(455): Error: this.__lambda6 has no value

On DMD nightly you even get a better error message saying that am error during CTFE happened :/
