Please make semicolons and braces optional. Unless they are explicitly required for marking blocks and endlines they are just wasted characters to people from prettier languages :-)
For those people who come from "ugly" languages like Java you could have a feature in the IDE which auto-inserted (and of course auto-removed) the braces/semicolons so that they felt at home too.
Are there really people that feel like the lack of adding semi-colons is bad? I understand why you want to be able to optionally terminate a line early for terseness but being required too is just more work.
But then I also know people who wax on about the meditative aspects of dish washing instead of buying a machine to do it.
