[stack] Looking for a combinator name

Hi all,

I am looking for a name for a combinator that is equivalent to:

In Cat: dip apply
Or in Joy: dip i

This turns out to be a very useful combinator when doing code
compression. Given two functions:

define f { a0 .. aN x b0 .. bN }
define g { a0 .. aN y b0 .. bN }

We can reduce the size by rewriting it as:

define h { [a0 .. aN] dip apply b0 .. bN }
define f { [x] h }
define g { [y] h }

Any suggestions would be appreciated.
