OK... I know that there are no signed numbers usually... But I wanted to try to 
change that...
So for _me_ in "-2" the minus is a sign... And in "- 2" the minus is a unary 
inversion operator... And in "1-2"  the minus is a subtraction operator (or an 
abbreviation for "1+-2" respectively (where the minus is a sign again))...
This can all be done quite elegantly with this context trick in the ll-file...

"1 -2^4" is no error in my program... it results in "-15".
It even says, that "- 2^4" is "-16", while "-2^4" is "16". 🥳

Do u think there will be any unwanted side effects?
