Proposal for discussion: COLNAMES & ROWNAMES

Looking into several different parts of R../src/library/base/R/*.R
has led me to the conclusion
that quite a bit of code doubling could be saved by using the following two
functions whose naming philosophy is derived from that of NROW() & NCOL():
COLNAMES <- function(x)
if(is.null(n <- colnames(x))) paste(seq(length=NCOL(x))) else n
ROWNAMES <- function(x)
if(is.null(n <- rownames(x))) paste(seq(length=NCOL(x))) else n
Do you have any positive or negative thoughts on this?
[a negative one that I had: ``yet another set of such *names functions !'']
Maybe, replying only to me -- who then would summarize -- is okay.
