[Python-ideas] Run length encoding

[Greg Ewing]

In my experience, RLE isn't something you often find on its own.
Usually it's used as part of some compression scheme that also
has ways of encoding verbatim runs of data and maybe other
things.

So I'm skeptical that it can be usefully provided as a library
function. It seems more like a design pattern than something
you can capture in a library.
