Not my experience with Nemo (in [A plea for int overflow checking as the default - #46 by Olof\_Salberger](https://discourse.julialang.org/t/a-plea-for-int-overflow-checking-as-the-default/3338/46) the Nemo integers did not improve the speed).  
Anyway, you see now why I said that the generalized GAP “numbers” which are union of everything from Int to  
Cyclotomics are beyond my capacity to implement in the current state of Julia. I really need to have an  
example `Union{Int,BigInt}` to look at so I understand how to extend it.
