May I disagree ?
I find missing ";" at end of lines *so* ugly. Ugly/not ugly depends on our observer's eyes.  From my programmer point of view, I prefer to mark clearly the end of the lines.
In many languages, it's safer to do it this way, and I thank the R developers to permit it. (in my opinion, it should even be mandatory). (By the way, marking the end of lines with a unique symbol makes also the job easier for the following treatment.) And yes, I'm also a C programmer ;-)

Why "<-" seems better than "=" is also quite mysterious for me. There was a discussion about this point recently I think. I believe in 99% of cases it's more for historical reason (and perhaps also for some "snob" reasons).

I am not at all a 20 years experienced R programmer, but I have written several hundreds of R lines those 6 last months, and until today didn't get any problem using "=" instead of "<-".

But I'll read your chain of arguments with interest.
