There is a great deal of variability in languages about that.

Python ends if lines with a : which might help the parser, but maybe not because it was a late addition to help readability. For me it adds work when moving code around because I have to add or remove the :

Ruby does totally without any terminator in that context (in other contexts it has its own {} or do...end). The parser keeps processing successive lines until it understands that what follows can't belong to the conditional. I prefer that approach because it's the language/compiler that has to help me, not the other way around.
