/**
|
|
* Accepts a function `fn` and a list of transformer functions and returns a
|
|
* new curried function. When the new function is invoked, it calls the
|
|
* function `fn` with parameters consisting of the result of calling each
|
|
* supplied handler on successive arguments to the new function.
|
|
*
|
|
* If more arguments are passed to the returned function than transformer
|
|
* functions, those arguments are passed directly to `fn` as additional
|
|
* parameters. If you expect additional arguments that don't need to be
|
|
* transformed, although you can ignore them, it's best to pass an identity
|
|
* function so that the new function reports the correct arity.
