/**
|
||
|
* Returns a curried equivalent of the provided function, with the specified
|
||
|
* arity. The curried function has two unusual capabilities. First, its
|
||
|
* arguments needn't be provided one at a time. If `g` is `R.curryN(3, f)`, the
|
||
|
* following are equivalent:
|
||
|
*
|
||
|
* - `g(1)(2)(3)`
|
||
|
* - `g(1)(2, 3)`
|
||
|
* - `g(1, 2)(3)`
|
||
|
* - `g(1, 2, 3)`
|
||
|
*
|
||
|
* Secondly, the special placeholder value [`R.__`](#__) may be used to specify
|
||
|
* "gaps", allowing partial application of any combination of arguments,
|
||
|
* regardless of their positions. If `g` is as above and `_` is [`R.__`](#__),
|
||
|
* the following are equivalent:
|
||
|
*
|
||
|
* - `g(1, 2, 3)`
|
||
|
* - `g(_, 2, 3)(1)`
|
||
|
* - `g(_, _, 3)(1)(2)`
|
||
|
* - `g(_, _, 3)(1, 2)`
|
||
|
* - `g(_, 2)(1)(3)`
|
||
|
* - `g(_, 2)(1, 3)`
|
||
|
* - `g(_, 2)(_, 3)(1)`
