Description:

Recently I needed to reduce a list to "every other" item in that list, i.e., the 1st item, the 3rd item, the 5th item, etc.

It occurred to me that in the future I might need, say, every third item rather than every other item, and that I might want to begin with something other than the first item on the list. It also occurred to me that I might want to specify a list separator other than a hard return, for either the input, the output, or both.

That's how this CF came to be.
