Less.js - strong nested rules?

问题

I love the ability of less.js to make nested rules. For example

.A{
    .B{
        width:50px;
    }
}

which results in

.A .B{
    width:50px;
}

But is there a way to make it result in this:

.A > .B{
    width:50px;
}

I´ve already tried to do this:

.A{
    &>.B{
        width:50px;
    }
}

But it does not work...

Thanks!

It's as simple as this:

.A {
    > .B {
        width: 50px;
    }
}
