For me it is only interesting because as I measured in my case the indirection is in case of array 0.7-0.9ns and in case of dict it is 3.5-5.5ns. I know this is something different… dict is much more complex, then how does this becomes 7ns (in case of 1 length array at the example Save dispatched function for later call - #22 by Marcell_Havlik)… it is just interesting, (the relatív difference is around 30x when more lengthy arrays are used).
