Why curly braces? Multiple function arguments are a form of
built-in tuple, so the syntax should be consistent:
auto (success, message) = callVoldemortFunction();
The only unresolved question is (as using the result of the
comma operator has been deprecated already): How to write a
unary tuple. My favourite is what python does: "(3,)". This is
however already accepted as a function argument list. I think
it is worth breaking though. Maybe we should deprecate it.
The curly bracket syntax looks straight out of DIP 32
https://wiki.dlang.org/DIP32
auto {x, y} = {1, "hi"};.
