It struck me only long after I wrote that post that Bartosz was not 
referring to composition in the traditional OO 'has-a' sense but rather 
in the functional or transactional sense. "Composition" in this sense is 
meant to refer taking algorithmic units (say, running Dijkstra's 
algorithm on a graph or maybe Tarjan's SCC-finding algorithm) and using 
them as building blocks to solve the problems you want to solve (e.g., 
interprocedural optimization).
