There are several problems with %+% :
- %whatever% should be open for use by the user and if R starts
taking them over they won't be
- %+% is ugly
- %+% is not consistent with other languages (the C-based syntax
of R is supposed to leverage off one's knowledge of other languages)

Well, two comments, in two non-compatible directions.
1. I have to say that I find the idea of using "+" to paste character
strings together aesthetically ugly.
IMO, one thing that makes functional object-based languages attractive
is that the generic function retains a consistent _function_,

1) I'd like to take a look at what is involved before commenting on
efficiency issues. They may not be what I thought they were (or at least,
being generic at all may be so big a hit that a few more cases may be
immaterial).
2) This + is clearly not commutative.
3) + is part of group generic.

This thread remains me of an old recurring (last May!) theme
which maybe fits well to Friday late afternoon...
There have been propositions to make "+" work in S (and R)
like in some other languages,
namely for character (vectors),
a + b := paste(a,b, sep="")
IIRC, when this theme cam
