/**
|
|
* Accepts a converging function and a list of branching functions and returns
|
|
* a new function. The arity of the new function is the same as the arity of
|
|
* the longest branching function. When invoked, this new function is applied
|
|
* to some arguments, and each branching function is applied to those same
|
|
* arguments. The results of each branching function are passed as arguments
|
|
* to the converging function to produce the return value.
