can you drop the need for the : at the end of the line if there's a newline? i.e. it seems like unnecessary syntax

That would make it much harder to parse in certain cases, both for the compiler and the human, given that it uses this same syntax to parse not just control structures, but also higher order functions / lambdas.

I like how ruby does it
