It's better visually. No dot, ., :, :., ::, ::., :::, etc. have increasing visual weight, which shows which are the more top-level operators without having to match up parentheses.

I see. It’s not clear how it would interact with operator precedence, however. For example, what would

    a * . b + c . + d * e

do?
