oh my think of how much code will break if they drop the old syntax. I see the same change for Do by the way. Anywhere else?

comment Histogram of a very large dataset?
answering myself, HistogramList[ data , {min, max, (max - min)/100}] takes about 5 minutes, while HistogramList[ data ] about 16. (I have 32G, i guess that made the difference).

comment Proof or find counterexample to inequality (in three vars)
with any specific n,r, you can use Limit[ q-> 0 or 1 ] to show the second factor is analytically zero. That along with the numerical plots is a "practical" proof. Of course a mathematician would want more..

consider the factors seperately. Try without the integer restriction

note the best approach may differ if the list is large and you just want a particular n vs if you want to tabulate f for all n..
