When viewed from a strategic perspective, a labeled rule base in a rewriting system can be seen as a restricted form of strategic expression (e.g., a collection of rules strictly composed using the left-biased choice combinator). This paper describes higher-order mechanisms capable of dynamically constructing strategic expressions that are similar to rule bases. One notable difference between these strategic expressions and rule bases is that strategic expressions can be constructed using arbitrary binary combinators (e.g., left-biased choice, right-biased choice, sequential composition, or user defined). Furthermore, the data used in these strategic expressions can be obtained through term traversals. A higher-order strategic programming framework called TL is described. In TL it is possible to dynamically construct strategic expression of the kind mentioned in the previous paragraph. A demonstration follows showing how the higher-order constructs available in TL can be used to solve several problems common to the area of program transformation.
