I've been thinking a little about the idea of returning tuples from functions,
w.r.t. Bugzilla 2628
(http://d.puremagic.com/issues/show_bug.cgi?id=2628). Would it be feasible to
solve this by making
struct[index] for any struct w/o an opIndex overload equivalent to
struct.tupleof[index]? This would be
trivial syntactic sugar, but would allow user-defined tuples in Phobos to look
like a builtin tuple, be
returned from functions, etc., while changing very little under the hood.
Furthermore, for functions that
take a tuple, we could allow structs to be implicitly cast to tuples, e.g.:
struct Foo {
uint u;
float f;
}
void doStuff(uint myInt, float myFloat) {}
Foo foo;
doStuff(foo); // Implicitly casts to foo.tupleof, works.
