4 | * Accepts a function `fn` and a list of transformer functions and returns a
|
---|
5 | * new curried function. When the new function is invoked, it calls the
|
---|
6 | * function `fn` with parameters consisting of the result of calling each
|
---|
7 | * supplied handler on successive arguments to the new function.
|
---|
8 | *
|
---|
9 | * If more arguments are passed to the returned function than transformer
|
---|
10 | * functions, those arguments are passed directly to `fn` as additional
|
---|
11 | * parameters. If you expect additional arguments that don't need to be
|
---|
12 | * transformed, although you can ignore them, it's best to pass an identity
|
---|
13 | * function so that the new function reports the correct arity.
