The idea to use "-" in the context of strings may have some merrit. Not as unary minus, but as sequence operation and shorthand for str.removesuffix(x):
s = 'abc' + 'def' - 'ef' + 'gh' giving s == 'abcdgh' Removing suffixes from strings is a rather common operation. Removing prefixes is common as well, so perhaps "~" could be mapped to str.removeprefix(): s = 'abcdef' ~ 'abc' giving s == 'def' In a similar way, "/" could be mapped to str.split(), since that's probably even more common: l = 'a,b,c,d' / ',' giving: l == ['a', 'b', 'c', 'd'] Looking at the examples, I'm not sure how well this would play out in the context of just using variables, though: s = a - s s = a / c s = a ~ p By adding such operators we could potentially make math functions compatible with strings by the way of duck typing, giving some really weird results, instead of errors.
