min does not work correctly in the "eval" form

```
p = {'p': [4,5]}
math.eval("min([1,2], p)", p)
>> 4
```

instead of `[1,2]`

This 

```
math.eval("min([1,2], [4,5])")
```

works correctly.

This does NOT work either:

```
p = {'p': [4,5]}
math.min([1,2], p['p'])
```

but that works:

```
p = {'p': math.matrix([4,5])}
math.min([1,2], p['p'])
```
