Ruby and CoffeeScript do and their syntax relies heavily on it.
- vidarh 14y agoFor Ruby at least "heavily" is a big exaggeration. It is significant as a token separator and in cases where inserting a line break makes the expression up to the line break a valid expression in itself, in which case it is treated as one. You pretty much only need to remember to separate tokens where lack of whitespace might create a different vald token, and ensure any expressions that you want to let span more than one line ends with something that expects following tokens to make a complete expression. Personally I can live with that easily. I can not live with significant indentation, on the other hand...
