There is `initializer_list` for TArray. It’s great. I can do next:

```
TArray<int32> = {1, 2, 3, 4, 5};

```

I think it would be nice works TMaps also:

```
TMap<int32, FName> map = { {1, "Hi!"}, {2, "Yo!"}, {3, "Lolz"} };

```

It possible if `TPair` will be extended with constructor with key and value, and `TMap` with `initializer_list`.

Thanks!

Would be a great addition. I hate having to do Map.Add for each element.

It is possible like this:

```
TMap<int32, float> map = { TPairInitializer<const int32&, const float&>(2, 5.f) };
```
