[SI-LIST] Why does lamination fail to prevent eddy currents at high frequencies?

I have seen a number of simple derivations explaining why it is a good idea
to laminate a conductor which lies in a magnetic field. The idea being to
slice up the material in the direction of the flux and hence break the path
of eddy currents. This is all very well and good, I then find it mentioned
in passing that this technique fails at high frequency but have not yet
found a good explanation as to why?
Would anyone care to have a stab at an explanation, or maybe poiint me in
the direction of one?
Thanks in advance
