N-th roots of complex numbers?

A quick question: is there a simple built-in method for computing the list
of all n-th roots of a complex number?  I can easily write a little
procedure myself, but I wonder if there's already something available?  So
that, for example, asking for the cube roots of 8i would return -2i,
-sqrt(3)+i,sqrt(3)+i.

Thanks,
Alasdair
