Alternatives to parentheses for groupingI've just begun reading Whitehead and Russell's "Principia Mathematica" available here and was surprised to find on page 9 a nice readable alternative to parentheses for grouping. Each operator is preceded and/or succeeded by some dots written as colons and periods. The more dots an operator has, the lower precedence it has. To take one of their examples (page 10), I find the dot version more readable and easier to type than the parentheses version. I'm curious if anyone here knows of other alternatives to parentheses for grouping. Prefix and postfix we've all heard of here, but do you have less well known ones? Hideous or beautiful I'd love to see them! Have any been tried in programming languages?
