Unexpected auto-concatenation of string elements:

string[] arr = ["a", "b" "c"];    // ["a", "bc"], length==2
int[] arr2   = [[1], [2] [3]];    // Error: array index 3 is out of bounds [2][0 .. 1]
                                  // Error: array index 3 is out of bounds [0..1]

Intended but on its way out. 2.072.0-b1 tells you it's deprecated.

It comes from C.

In C you can write stuff like:

char* foo = "Foo is good but... "
            "... bar is better!";

Eg static string concatenation for multiline/macros etc.

Think it was implemented this way to provide better support for converting c codebases.
