+1 from me on this. Scheme has an analogous feature, btw, which is
very elegant. I'd love to see this in Python.

As has been pointed out, you can go further and collapse this
into

def timesn(n)(f)(y):
    return n * f(y)

This means it would also be useful for non-parametric decorators
as well, e.g.

def fivetimes(f)(x):
    return 5 * f(x)
