What is the most efficient way of applying a function to all the elements of
an iterable while discarding the
result (i.e. operations are done only for side-effects).
For example if I want to save all elements in a list of items (and am not
interested in what save() returns), the
simplest way is:

Not an unreasonable assumption, but it

I will. I thought that this question would have an answer in a generic
python idiom.
