isRandomAccessRange on static array

[Brad Anderson]

A user in IRC was having difficulty using std.algorithm.sort on a 
static array.  It appears to be due to static arrays don't pass 
the isRandomAccessRange constraint.

    static assert(isRandomAccessRange!(uint[5]));
Results in:

    Error: static assert  (isRandomAccessRange!(uint[5u])) is 
false

Is this a bug or am I missing something?
