Ah, but if you let your C# (or Java?) exposure influence you, foo = foo + bar looks ok even if OUString is considered immutable. The old object that the foo variable refered to is lost (unless it had other references), and foo is set to refer to a new object which is the concatenation of the old foo and bar. Not any stranger than tem = foo + bar; foo = null. But foo += bar looks weird, as it seems to say that the immutable object that foo refers to gets something appended to it. At least thinking of C# is how I explain to myself why I like one but not the other... But sure, I know that variables and objects in C++ is a completely different thing than in C# or Java, despite superficial similarities --tml _______________________________________________ LibreOffice mailing list LibreOffice@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/libreoffice
