I think these two simple templates could be added to std.traits. Afaik there is no way around defining templates for this:

/***
 * Get the referenced type of an array.
 * Example:
 * ---
 * import std.traits;
 * int[] foo;
 * ValueType!(foo) x;   // x is declared as int
 * ---
 */
template ValueType(T : T*)
{
    alias T ValueType;
}

/***
 * Get the referenced type of an pointer.
 * Example:
 * ---
 * import std.traits;
 * int* foo;
 * ValueType!(foo) x;   // x is declared as int
 * ---
 */
template ValueType(T : T[])
{
    alias T ValueType;
}

Sorry wrong newsgroup. But - since ready-to-use code is included - this might not be so totally wrong.

I think you mixed the comments up :)
