I call the idea the 80/20 Split, or 'Convenience Functions'.
You have a powerful, highly generalized function that can do most
anything, and has an interface to prove it.
Then, a collection of 'Convenience Functions' to constrain that "Swiss
Army Knife" to handle 80% of the use-cases, while still letting Ye
Power User dig a little deeper.
The challenge is to keep the Convenience Function population low, so
that you don't arrive at 8,020 different functions in the interface.
Go, Python!
