Deprecation of implicit string concatenation

[Johan Engelen via Digitalmars-d]

Since 2.072, implicit string concatenation is deprecated [1].
Can someone give me a link to the discussion about this?
I am wondering about the language spec changes involved.

```
  "abc"
  "def"
```
means something different than
```
  "abc"
  ~ "def"
```
right? (for example because opBinary!(“~”) can be overloaded)
The first one will apparently no longer be allowed in the future.

Did we lose the ability to break strings across lines?

Thanks,
  Johan
