First we'll add a definition:

ability DeathStar where
  attack : Text -> ()

spaceAttack1 x =
  y = attack "saturn"
  z = attack "neptune"
  "All done"

Add it to the codebase:

.> add

Now we'll try to add a different definition that runs the actions in a different order. This should work fine:

spaceAttack2 x =
  z = attack "neptune"
  y = attack "saturn"
  "All done"

.> add

Previously, this would fail because the hashing algorithm was being given one big let rec block whose binding order was normalized.
