Specifically in Python, if you're appending lines of text, for example, then you have to add a \ before the newline. Also in Javascript if you omit the semi-colon then sometimes the interpreter gets confused and functionality gets jumbled. Sorry if that's not that specific. I just in general prefer semi-colons being required, because then it fails fast rather than producing subtle bugs later.
