True, though less readable I think. If we're going to go as far as arbitrary expressions, let's discuss making very common scripting tasks easier.
There's already a way to make common scripting tasks easy: use the preferred shell for your preferred platform.
That said, if anyone really wants to advance the state of the art in Python's "embedded shell scripting" capabilities, then I'd highly recommend exploring Julia's capabilities in that area and seeing how to produce a comparable system using runtime processing of strings in Python: http://julia.readthedocs.org/en/latest/manual/running-external-programs/
Combining a system like that with f-strings (and/or i-strings) would then allow ready interpolation of Python variables into command lines using either *nix or Windows appropriate syntax.
