# Solving a simple system of inequalities

I asked:

```
var('x','y','z')
solve_ineq([x<y,y<z])
```

and got:

```
[[y < z, x < y]]
```

What should I do to get the expected inequality:

```
x < z
```

?

`x<y,y<z`

are **not** equivalent to `x < z`

, for example `{x:1,y:0,z:3}`

satisfies the second equation but not the first.

By the way, on Sage 7.0.beta3, i got:

`[[x < y, y < z, x < z]]`
