The thing that I would like to get rid of is recycling vectors. In my
experience with R, this is the biggest danger, directly in data
analysis itself, not just in programming. If there is going to be a
compatibility mode, I suggest that this be turned off by default as
well as stretchy vectors.
  I see compatibility mode as something to be turned on in those rare
occasions when it is necessary to run some S-Plus code without trying
to fix it up for R. Something like being able to compile old Fortran 4
code with a Fortran 77 or later compiler, or non-ANSI C code.
