curryr can be used when the arguments need to be inserted at the end. In other words, (curryr list 1 2) will produce a function expecting some new-arguments .... When called, that new function will in turn call (list new-arguments ... 1 2).

my-curry: implement your own version of curry. Your version should behave identically to curry, but need only work on procedures with fixed arity. E.g.,
> ((my-curry even?) 2)
#t
> (((my-curry cons) 1) 2)
'(1 . 2)
> ((my-curry cons 1) 2)
'(1 . 2)
