When to use template meta programming ?

  C++(11) library to implement custom binary communication protocols

  

I suppose if you develop something that is going to be used in a single project / product without much of a customization, then meta-programming is not really justified. The meta-programming is justified in many cases when you implement some kind of a library, which can be used in multiple independent products, and these uses may require some product specific customizations. For example, I'm developing a solution for implementing binary communication protocols for embedded systems in C++, called CommsChampion Ecosystem. The core component of which is the COMMS library. Every single use of this library requires different customization. Every application may require different polymorphic interface to handle its message objects. I use template meta-programming there to define virtual functions only needed by the application and not adding unnecessary ones. I also use template meta programming to allow customization of the storage data structures and may use different, more optimized code for some.
