Re: How to make a struct containing an associative array to deeply copy (for repeated usage in foreach) ?

[rkompass via Digitalmars-d-learn]

To solve the problem with the 1-variable and 2-variable versions 
of foreach I
tried opApply and found that the compiler prefers it over opSlice 
and opIndex() (the latter without argument).

My code:
```d
        int opApply(int delegate(Variant) foreachblock) const {
                int result = 0;
                foreach(val; dct) {
                        result = foreachblock(val);
                        if (result)
                                break;
                        }
                return result;
        }
        int opApply(int delegate(Variant, Variant) foreachblock) const {
                int result = 0;
                foreach(key, val; dct) {
                        result = foreachblock(key, val);
                        if (result)
                                break;
                }
                return result;
        }
```
So I'm fine with this now.
