[phobos] phobos commit, revision 1516

[Andrei Alexandrescu]

I don't think tie() is good for us, sorry for not voicing this earlier.

Since it takes the addresses of references and it escapes them into a 
struct for later use, it is inherently unsafe.

I suggest we replace tie() with a typesafe alternative, for example 
scatter(). Instead of

int    n;
double d;
tie(n, d) = tuple(10, 3.14);
assert(n == 10);
assert(d == 3.14);

we have the safe alternative:

int    n;
double d;
scatter(tuple(10, 3.14), n, d);
assert(n == 10);
assert(d == 3.14);


What do you all think?

Andrei
