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...

It even says, that "- 2^4" is "-16", while "-2^4" is "16". 🥳 Do u think there will be any unwanted side effects? -arne
