Improved syntax for gridded/scaled interpolation

If I've got some gridded `x` and `y` data already sitting around, its a bit of a pain to interpolate. AFAICT the best way to do it is something like this:

``` julia
x = [2,4,6,8]
y = [1,4,3,6]

itp = scale(interpolate(y,BSpline(Linear())),x[1]:(x[2]-x[1]):x[end])
```

Is there some way this could be shortened to something like

``` julia
itp = interpolate(x,y,BSpline(Linear()))
```

instead?
