If `t`

is a tuple of 2 elements of type `A`

and `B`

, what does

```
a, b = t
```

do ? Is it equivalent to

```
a = t[1]
b = t[2]
```

or does it do something else ?

While updating Polyhedra to Julia v0.7, I hit a weird issue where `a`

and `b`

have types `Vector`

instead of `A`

and `B`

as expected. Moreover, when asking for the length of `b`

I get a number that seems to large to have a vector of this size fitting in memory.
