It isn't slow if you actually use the power: your program
compiles and runs with amortised O(1) dispatch.
The equivalent C++ program can be written, and requires
a base for each method, and a base for every possible
combination of methods .. and whilst you're uploading
the sources for these combinations to the Klingon computer
network fortunately the universe suffers heat death.
[This is a good thing because there's no way you were
going to be able to pay Enterprise ISP P/L the network
traffic charges]
