lapply( *, names) -- bug ?!

[Martin Maechler]

This came on S-news

The more direct test being

sapply(c(a=1,b=2), names)

Problem:  
	  R ("all" versions) 
	  behaves the same as S+5.1, which is wrong IMO.

{since some might disagree,  I didn't yet post to R-bugs ..}

Subject: [S] Feature or bug?

In S-PLUS 3.3 (DEC Alpha) and S-PLUS 2000,

> z <- c("a"=1, "b"=2)
> lapply(z, function(x)names(x))
$a:
[1] "a"

$b:
[1] "b"

But in S-PLUS 5.1 (Linux),

> z <- c("a"=1, "b"=2)
> lapply(z, function(x)names(x))
$a:
NULL

$b:
NULL

Is this a new feature of S-PLUS 5? Do I miss anything in
S-PLUS 5? Thank you for your help.
