objects.summary() I think it was.

It always bothered me that the Nth thing you teach Unix users is 'ls' 
and the N+1th thing is 'ls -l' (for very small N). Then you teach them 
R, and there's no 'ls -l' equivalent immediately obvious.

  Not sure what such a function could show, there being no permissions, 
or dates on R objects, but object.size() and class/mode at least would 
be useful.

  So is something like this in CRAN? I say +1 to putting it in the base
