If end of line always means end of statement, by all means get rid of semi colons. If some non-trivial algorithms is used to infer end-of-statement boundaries that is more complicated than detecting end-of-line, then...there will be subtle problems.

I went through this transition before in Scala, the error messages got a lot worse after semi-colon inference was added. I wound up telling people to add semi-colons to their code when they were scratching their head at some sort of parse/type error message.
