comment Expansion of a hypergeometric function takes ages with Mathematica 9 and 10 (regression?)
I confirm it seems to take a long time in mathematica 10.0.2

@halirutan would it be possible to modify your answer so that it takes wildcards? Such as StringProperties[NonlinearModelFit, "Table"] which would be the equivalent of ?*Table* ?
