We had some discussions on the string concatenation operator and agreed on
"+" and "cat"
However, "+" is currently used only for addition, and so is not backward
compatible. The feedback from internal users is breaking backward
compatibility is BAD.
We have also discussed using other symbols such as "+=" or "!" etc, but
none of them feels right. So I propose to drop "+" and only use "cat"
as the concat operator.
Let me know if there are other opinions. Thanks.
