I wouldn't say that there isn't a wayâ?¦

Here's a link to the same question on Mathematica.SE (and the answer I like):

http://mathematica.stackexchange.com/a/5574/12

Block[{$ContextPath},  Needs["Combinatorica`"]]

I always load Combinatorica like this in version 8 and later.

I should note here that if you use the ToCombinatoricaGraph function 
from the GraphUtilities package, it'll force-add Combinarotica` to the 
context path.  I did point out how this is rather inconvenient to 
support at wolfram.com, but it wasn't fixed.
