   2 Compile-time sequences of types are one of the basic concepts of C++
   3 template metaprogramming. Differences in types of objects being
   4 manipulated is the most common point of variability of similar, but
   5 not identical designs, and these are a direct target for
   6 metaprogramming. Templates were originally designed to address this
   7 exact problem. However, without predefined mechanisms for
   8 representing and manipulating *sequences* of types as opposed to
   9 standalone template parameters, high-level template metaprogramming
  10 is severely limited in its capabitilies.

  12 The MPL recognizes the importance of type sequences as a fundamental
  13 building block of many higher-level metaprogramming designs by
  14 providing us with a conceptual framework for formal reasoning
  15 and understanding of sequence properties, guarantees and
  16 characteristics, as well as a first-class implementation of that
  17 framework |--| a wealth of tools for concise, convenient,
  18 conceptually precise and efficient sequence manipulation.
