The C++ "buck" operator

Syntactic sugar for a more expressive way of returning multiple values from a function. Defines a new syntax, using the dollar sign, to bind multiple values together.

WARNING: This is probably a stupid idea, use this at your own risks.

Example: declaring a function

$<int, string> get_username();

Example: returning multiple values

return $(0, "root");

Example: assigning the result to variables

int id;
string name;

$(id, name) = get_username();

Example: ignoring some values

string name;

$(, name) = get_username();

Remarks:

• it requires C++11
• it's just a wrapper on top of std::tuple
• it triggers the GCC warning dollar-in-identifier-extension
