And, spurred on by another thread, this has become possible.
Make a file like so, install it if you wish.
import sys

This lets you do this:
python unicode_escape.py "a = [] ##\nfor x in range(100): ##\n
> a.append(x) ##\n a.append(x**2) ##\nprint(a)"
It's ugly, but it works and only takes one line.
