IMO there's no chance of confusing it with a function call, since a function call would be illegal in the context in which it's used, and people are naturally more likely to add a semicolon without thinking about it, and if I design the macro so that a semicolon is required it will interact more smoothly with editors and pretty-printers. So I can't see any good reason not to require the semicolon. Arguments?
I find a lot of macros that end without semicolons wind up confusing my editor's code indenter (in this case, cc-mode for emacs.) When such macros appear I start to get weird formatting that I don't like. For that reason, I always try to make macros that take parameters able to end with semicolons. -- Chris
