Once the graph of dependencies between components gets complex, passing all those beans as positional arguments might get tiresome, and type-directed autowiring begins to seem more appealing. Most of the information required for constructing the graph resides in the types themselves, after all. DI frameworks also provide aspect-oriented-programming services (transactionality, logging...). Doing that with plain functions in an arity-polymorphic way is possible, but not completely trivial, in my (Haskell) experience. http://web.cecs.pdx.edu/~ntc2/haskell-decorator-paper.pdf |
