Python uses +.
There's much historical precedence for + meaning concatenation, and much
historical experience with the resulting ambiguity. The famous example is:
"123" + 4

int[] array;
array + 4
Does that mean append 4 to array, or add 4 to each element of array? What if you
want to create a user defined type that supports both addition and concatenation?
Use + for addition, ~ for concatenation, and all these problems go away.
