Not sure if it's a good idea, but maybe try: foo-bar # kebab-case foo−bar # subtraction foo minus bar # subtraction? (infix identifier "minus") foo - b

Not sure if it's a good idea, but maybe try: foo-bar # kebab-case foo−bar # subtraction foo minus bar # subtraction? (infix identifier "minus") foo - bar # subtraction (infix identifier "-") foo − bar # subtraction (operator symbol) using \u2212 as a explicit subtraction operator for people who really can't stand having 'extra' whitespace?
