	Much, but not all, of the functions in Combinatorica have been
added to Mathematica's core.  Subsets is one example.
	Best,

Newbie question (by example):
How can I access KSubsets (which I believe is only in Combinatorica)
without hiding the kernel's graph functions?  (I.e., I would like to be
able access the Combinatorica functions *only* when I specify e.g.
Combinatorica`KSubsets, so that  if e.g. I just use the short name Graph
this refers to System`Graph.

So I don't want to say e.g.
Needs["Combinatorica`"]
because then I cannot just use Graph to refer to System`Graph.

Ideally, I'd like an equivalent to a name import from a Python package
(e.g., ``from mypackage import myfunction``).

Short of that, I thought about reordering the $ContextPath, but I'm not
sure this is a good idea (or how to do it correctly).

Hope that's clear enough.

Thanks,
Alan Isaac
