This question on Stackoverflow http://stackoverflow.com/questions/32504524/is-value-of-xfx-unspecified-if-f-modifies-x was asked for C++ recently. I think it makes sense to ask it for Julia, too, given its pass-by-sharing and we-are-all-consenting-adults semantics, and I was wondering what the answer is. Of course I can test it on an example, but I was wondering if this detail is defined explicitly in the specifications/docs.
Thanks!
