I'm not sure about the metric of "syntactically significant", though. Semicolons are definitely important for the compiler, but they're usually very unimportant for the human writer and reader of the code - if they are present, they can be ignored, and if they are not present, then the IDE can indicate that fairly reliably, regardless of where in the code it sits. When editing, they are rarely particularly present in my mind. And given that for the compiler - the only entity that does need to be aware of them - it doesn't matter at all where they go, it doesn't seem useful to emphasise them in this way.
