Is there some easy way to compare multiple numbers to one number in C++11?

I'm just starting to try C++ 11, and was wondering if I could improve this line sort of thing from my C++03 code:

if (a == b || 
	a == c || 
	a == d || 
	a == e
	)
{
// do something
}

I wasn't able to find anything in the new arithmetic functions, but if there is something that could be used to avoid mentioning "a" 4 times in such a situation that would be nice.. Thanks.

I don't know of any way to avoid it.
