So what's "x-1"? I suppose you could use some *different* symbol in the literal syntax for negative numbers. I had a calculator once that used a different symbol (looked like a small superscript minus sign) for it. But Python is limited to ASCII for basic syntax elements for good reasons.
APL uses "¯" ('\N{MACRON}'), e.g. "¯1".
