Float equality is inconsistent.

```
> let
|   p = (0/0, 1)
|   q = (0/0, 1)
| in
|   p == q
|   
False : Bool
```

```
> let
|   p = (0/0, 1)
| in
|   p == p
|   
True : Bool
```

Since NaN does not equal NaN, Float is not reflexive under equality. Therefore a quick object pointer comparison leads to inconsistency, the same values are equal one way, and not the other.
