  Abstract:  Template metaprogramming is an emerging new direction in C programming for executing algorithms at compilation time. Despite that template metaprogramming has a strong relationship with functional programming, existing template metaprogram libraries do not follow the requirements of the functional paradigm. In this paper we discuss the possibility to enhance the syntactical expressivity of template metaprograms using an embedded functional language. For this purpose we define EClean, a subset of Clean, a purely functional lazy programming language. A parser, and a graph-rewriting engine for EClean have been implemented. The engine itself is a compile-time template metaprogram library using standard C language features. To demonstrate the feasibility of the approach lazy evaluation of infinite data structures is implemented.
