Constraint to enforce that a given type is an array, or pointer, or user defined type which is amenable to subsripting (i.e.

defines operator[] or operator X*())

Parameters:

T

It may be used as follows:

  typedef std::vector<int>  vec_t;

  stlsoft::must_be_subscriptable<int*>();   // Ok
  stlsoft::must_be_subscriptable<vec_t>();  // Ok
  stlsoft::must_be_subscriptable<double>(); // Compile error!
