Forgot to point out that the original point with mentioning
Python in the thread is:
1. Compiled static languages still have a long way to go with
expressiveness.
2. Generic operations on double will lead to wrong results. What
happens if your first value is very large? You loose the
accumulation of the smaller values, in the worst case you only
get the first value. Thus you will have to sort the values by
exponent before accumulating or convert it into a different
format.
So yes, C++ iterators and D ranges are kind of cool, but cannot
beat a well engineered library and a good mapping to it on the
language side. (Python is of course not optimal in any way.)
