+   * @ingroup functors
+   *
+   *  Binders turn functions/functors with two arguments into functors
+   *  with a single argument, storing an argument to be applied later.
+   *  For example, a variable @c B of type @c binder1st is constructed
+   *  from a functor @c f and an argument @c x. Later, B's @c
+   *  operator() is called with a single argument @c y. The return
+   *  value is the value of @c f(x,y). @c B can be @a called with
+   *  various arguments (y1, y2, ...) and will in turn call @c
+   *  f(x,y1), @c f(x,y2), ...
+   *
+   *  The function @c bind1st is provided to save some typing. It takes the
+   *  function and an argument as parameters, and returns an instance of
+   *  @c binder1st.
+   *
+   *  The type @c binder2nd and its creator function @c bind2nd do the same
+   *  thing, but the stored argument is passed as the second parameter instead
+   *  of the first, e.g., @c bind2nd(std::minus<float>(),1.3) will create a
+   *  functor whose @c operator() accepts a floating-point number, subtracts
+   *  1.3 from it, and returns the result. (If @c bind1st had been used,
+   *  the functor would perform <em>1.3 - x</em> instead.
+   *
+   *  Creator-wrapper functions like @c bind1st are intended to be used in
+   *  calling algorithms. Their return values will be temporary objects.
+   *  (The goal is to not require you to type names like
+   *  @c std::binder1st<std::plus<int>> for declaring a variable to hold the
+   *  return value from @c bind1st(std::plus<int>(),5).
+   *
+   *  These become more useful when combined with the composition functions.
+   *
+   *  These functions are deprecated in C++11 and can be replaced by
+   *  @c std::bind (or @c std::tr1::bind) which is more powerful and flexible,
+   *  supporting functions with any number of arguments.  Uses of @c bind1st
+   *  can be replaced by @c std::bind(f, x, std::placeholders::_1) and
+   *  @c bind2nd by @c std::bind(f, std::placeholders::_1, x).

+   * thinking about searching for a value in a sorted range, we view
+   * that as an important special case of a more general algorithm:
+   * searching for the partition point in a partitioned range.  We
+   * also add a guarantee that the old wording did not: we ensure that
+   * the upper bound is no earlier than the lower bound, that the pair
+   * returned by equal_range is a valid range, and that the first part
+   * of that pair is the lower bound.</em>
+   *
+   * The actual effect of the first sentence is that a comparison
+   * functor passed by the user doesn't necessarily need to induce a
+   * strict weak ordering relation.  Rather, it partitions the range.

+// Secondly, from the point of view of ease of use, type-based compile-time
+// information is -not- *that* convenient.  On has to write lots of
+// overloaded functions and to hope that the compiler will select the right
+// one. As a net effect, the overall structure isn't very clear at first
+// glance.
+// Thirdly, partial ordering and overload resolution (of function templates)
+// is highly costly in terms of compiler-resource.  It is a Good Thing to

+   *  array.  The start offset is the index of the first element of the array

+   *  to begin at an array element described by the previous dimension.  The
+   *  size array and stride array must be the same size.
+   *
+   *  For example, if you have offset==3, stride[0]==11, size[1]==3,

+// This compiler refers to "Regular Expression Matching Can Be Simple And Fast"
+// (http://swtch.com/~rsc/regexp/regexp1.html"),
+// but doesn't strictly follow it.
+//
+// When compiling, states are *chained* instead of tree- or graph-constructed.
+// It's more like structured programs: there's if statement and loop statement.
+//
+// For alternative structure (say "a|b"), aka "if statement", two branches
+// should be constructed. However, these two shall merge to an "end_tag" at
+// the end of this operator:
+//
+//                branch1
+//              /        \
+// => begin_tag            end_tag =>
+//              \        /
+//                branch2
+//
+// This is the difference between this implementation and that in Russ's
+// article.
+//
+// That's why we introduced dummy node here ------ "end_tag" is a dummy node.
+// All dummy node will be eliminated at the end of compiling process.
