2695 - todo for recipe variables

Basically I need to make these tests work:

- Test 1: specializing while saving shape-shifting recipe literal
recipe f a:address:shared:_elem -> b:address:shared:_elem [
  local-scope
  load-ingredients
  reply a
]

recipe main [
  local-scope
  {x: (recipe (address shared number) -> (address shared number))} <- copy f
  y:address:shared:number <- new number:type
  *y <- copy 34
  z:address:shared:number <- call x, y
  $print *z, 10/newline
]

- Test 2: passing recipe literal to higher-order recipe
recipe g x:address:shared:number, {h: (recipe (address shared number) -> (address shared number))} -> y:address:shared:number [
  local-scope
  load-ingredients
  y <- call f, x
]

recipe main [
  local-scope
  x:address:shared:number <- new number:type
  *x <- copy 34
  y:address:shared:number <- g x, f
  $print *y, 10/newline
]
