- Converts expression containing literal values to their values:
'{1}
->1
,'{2}
->2
, ...- For all primitive types and
String
- Converts an expression that constructs a copy of its value.
- This expression must be some kind of data structure (
Some
,List
,Either
, ...) - Calls to
new X
orX.apply
can be lifted into its value - Arguments of constructors can be recursively unlifted
- This expression must be some kind of data structure (
