To prepend would be <0,'my string'> to append would be <'my string',0>; the second case is what you'd use for null terminated strings.

Well, It depends on the operations you're doing on them and the libraries you're using, but here is a general rule, if the string have a Known length and a defined starting point then No need for the 0, else use the 0 at the end of the string(this way is more flexible than the fist, specially if you're working on Windows or using C's library), so I prefer using <'MySting', 0> over <'MySting'> in most cases.

I agree,but here seems a special case, the < > is macro of library that (so far) we don't know how is implemented. Such macro can expand to put a 0-byte at end-of-string,it's want to he know. By reading the doucumentaion is only way to know.
