They are not issues in Go, but Walter is strongly against optional 
semicolons, as bearophile said. Me and others (like you) like optional 
semicolons, but since Walter doesn't and it's his language, that will 
not change.

I personally understand much better the code without semicolons, like in 
Ruby and Python. And making a parser that way isn't that much difficult, 
and error recovery is as powerful.
