Scrapping your inefficient engine: using partial evaluation to improve domain-specific language implementation

Partial evaluation aims to improve the efficiency of a program by specialising it with respect to some known inputs. In this paper, we show that partial evaluation can be an effective and, unusually, easy to use technique for the efficient implementation of embedded domain-specific languages. We achieve this by exploiting dependent types and by following some simple rules in the definition of the interpreter for the domain-specific language. We present experimental evidence that partial evaluation of programs in domain-specific languages can yield efficient residual programs whose performance is competitive with their Java and C equivalents and which are also, through the use of dependent types, verifiably resource-safe. Using our technique, it follows that a verifiably correct and resource-safe program can also be an efficient program.
