This is a typical example:

• The documentation (currently) of the function warns not to use it this way;

• This is a rather perverse use of the function(s) that would be unlikely unless you’re trying to break things;

• The discussion on the issue page demonstrates the exact opposite of a culture not caring about correctness;

• This kind of stuff doesn’t matter to all the scientists who are actually using Julia to do real work.

Nevertheless, sum!() and friends should be, somehow, made to avoid this problem, certainly.
