Searching the mailing list archives for 'block comment' provides another hairy solution from Philippe Grosjean, which involves redefining '!' for character arguments: http://tolstoy.newcastle.edu.au/R/e2/help/06/10/2168.html I don't know if R-core would consider putting block comments (maybe with /* */ syntax) into R. There are problems with block comments since they have very non-local effects - once you've scrolled down a bit, how can you tell if code is commented or not? And modern editors are capable of commenting out large blocks with the '#' character, so maybe there's no demand. Python doesn't have them (which is my benchmark for language qualities at the moment): http://www.velocityreviews.com/forums/t355236-why-no-block-comments-in-python.html On reflection, block comments in R gets a -1 from me.
