Implementation of polymorphic single dispatch via Virtual Tables (a la C++'s polymorphism) in Julia.
Mostly this was just for fun. This could maybe also be used for a baseline comparison of the performance of dynamic multiple dispatch in julia against a single dispatch case.
Here is the current state of the comparisons, per the tests. Julia's dispatch is the first number, and the package's dispatch is the second number:
