Sexp move (and other structural edit navigation)

[ypytomets]

It's a question or feature request:

• Is there a command(s) that would let user move sexp around, without explicit cutting/yanking, like:

function () {
  h█elper("move me")
  return true
}
there()
here()

• Do sexp-up+sexp-next+sexp-down:

function () {
  return true
}
t█here()
here(helper("move me"))

• And sexp-previous+sexp-over-down:

function () {
  return true
}
t█here(
  here(helper("move me"))
)

• And sexp-down+sexp-transpose-nested:

function () {
  return true
}
h█ere(
  there(helper("move me"))
)

Maybe sexp-yank-after, sexp-yank-into, sexp-yank-around, sexp-yank-replace (with/without nested?) would be handy too. And/or some combinations of yank-ing and opening/shrinking the new line at certain part of the sexp (inside, around, etc). Also sexp-remove-upper (but keep nested), and sexp-remove-nested (or sexp-rm-down -- remove nested sexp without moving the cursor)?
