Yes my fault, I try to simplify too much. Here is more detailed description

Code which works on 2.060 and don`t compile on 2.061

module main;

import std.algorithm;
import std.array;

immutable struct Column {

    string opAssign(V)(V tValue) {
        return tValue;
    }
}

class Ob2 {
    enum : Column {
        COLUM_A = Column()
    }

    immutable COLUMNS = [
        COLUM_A,
    ];
}

immutable test1 = Column();

void main(string[] args)
{
    string where = test1 = "something"; // works ok
    std.stdio.writeln(where);
    where = (Ob2.COLUM_A = "something else"); // works 2.060, dont compile on
2.061
    std.stdio.writeln(where);
}


However I find out more interesing thing. This code is almost same however it
doesn`t work on 2.061 neither 2.060:

module main;

import std.algorithm;
import std.array;

immutable struct Column {

    string opAssign(V)(V tValue) {
        return tValue;
    }
}

class Ob2 {
    enum : Column {
        COLUM_A = Column()
    }

    // comment this code make it not compilable in 2.060
    /*immutable COLUMNS = [
        COLUM_A,
    ];*/
}

immutable test1 = Column();

void main(string[] args)
{
    string where = test1 = "something"; // works ok
    std.stdio.writeln(where);
    where = (Ob2.COLUM_A = "something else"); // dont compile on 2.060 and
2.061
    std.stdio.writeln(where);
}
