| Compile-time sequences of types are one of the basic concepts of C++ |
| template metaprogramming. Differences in types of objects being |
| manipulated is the most common point of variability of similar, but |
| not identical designs, and these are a direct target for |
| metaprogramming. Templates were originally designed to address this |
| exact problem. However, without predefined mechanisms for |
| representing and manipulating *sequences* of types as opposed to |
| standalone template parameters, high-level template metaprogramming |
| is severely limited in its capabitilies. |
| |
| The MPL recognizes the importance of type sequences as a fundamental |
| building block of many higher-level metaprogramming designs by |
| providing us with a conceptual framework for formal reasoning |
| and understanding of sequence properties, guarantees and |
| characteristics, as well as a first-class implementation of that |
| framework |--| a wealth of tools for concise, convenient, |
| conceptually precise and efficient sequence manipulation. |
