----------------------------------------
Feature #11161: Proc/Method#rcurry working like curry but in reverse order

----------------------------------------
currenty with curry you can only replace elements in order
`#rcurry` should be added to be able to return the last parameter first.


```ruby
def abc(a,b); "a=#{a}, b=#{b}"; end
c= method(:abc).curry

c[1,2] #=> "a=1, b=2" 
c[1][2] #=> "a=1, b=2" 
```

i image rcurry to be like that:
```ruby
def abc(a,b); "a=#{a}, b=#{b}"; end
c= method(:abc).rcurry(2)

c[1,2] #=> "a=2, b=1" 
c[1][2] #=> "a=2, b=1" 
```

because of optional parameters, rcurry might be only be used when giving the arity
