There is a variance bug such that the following cast is allowed to go through:
```
> =a 12
> =core1 ^? |=(b=@ a)
> =a "hello"
> =core2 ^? |=(b=@ a)
> ^+(core1 core2)
```
This should not be! The code in `hoon.hoon` is correct -- it turns out that the jet is wrong however. It falsely returns "yes" for a nest in which two cores have identical code. Obviously that's not enough to guarantee sameness of type. So I've removed the offending lines.

Casting with a `^&` rune example fails because of a minor jet typo:
```
> ^+(^&(|=(@ 15)) |=(@ 15))
-gene.[%ktpd %brts [%base %atom 0] %sand %ud 15]
play-open-z
ford: %slim failed:
ford: %ride failed to compute type:
```
The above cast should go through. This fix makes that happen.
A bug causes this cast to go through:
```
^+(|=(@ 15) ^&(|=(@ 15)))
```
It should nest-fail. This change makes the cast work correctly with the metal wrapping runes `^&`, `^|`, and `^?`.
In the current release candidate, this happens:
```
> ^?(^|(add))
wrap-gold
ford: %slim failed:
ford: %ride failed to compute type:
```
This is a jet mismatch from `+wrap`, I believe:

You should be able to convert iron and zinc cores to lead.
