Hello! I am trying to learn metaprogramming in Julia, and the first problem I’ve had is the following. When I try to define an arbitrary Wilkinson-type polynomial (for instance, `p_5(x) = (x-1) * (x-2) * (x-3) * (x-4) * (x-5)`

is the polynomial of degree 5), I’ve written this function:

```
function wp(n::Int)
ex = :(x-$n)
for i=n-1:-1:1
ex = :($ex*(x-$i))
end
return ex
end
```

and it gives an expression which seems correct. However, I don’t know how to evaluate it for some x, say x=1.3. Could you help me? Thank you.
