@singledispatch is not designed to bring Java-style method overloading to Python. A single class with many overloaded variations of a method is better than a single function with a lengthy stretch of if/elif/elif/elif blocks. But both solutions are flawed because they concentrate too much responsibility in a single code unit—the class or the function. The advantage of @singledispatch is supporting modular extension: each module can register a specialized function for each type it supports. In a realistic use case, you would not have all the implementations of generic functions in the same
