37. def unnest(arg0: Tree, args: List[Tree])(makeStat: (Tree, List[Tree]) ⇒ Tree): Tree

    Same as above, for two arguments

39. def unnest(arg: Tree)(makeStat: (Tree) ⇒ Tree): Tree

    

    Same as above, for a single argument

40. def unnest(args: List[Tree])(makeStat: (List[Tree]) ⇒ Tree): Tree

    

    Unnest complex constructs in argument position in temporary variables

    Unnest complex constructs in argument position in temporary variables

    If all the arguments are JS expressions, there is nothing to do. Any argument that is not a JS expression must be unnested and stored in a temporary variable before the statement produced by makeStat.

    But *this changes the evaluation order!* In order not to lose it, it is necessary to also unnest arguments that are expressions but that are supposed to be evaluated before the argument-to-be-unnested and could have side-effects or even whose evaluation could be influenced by the side-effects of another unnested argument.

    Without deep effect analysis, which we do not do, we need to take a very pessimistic approach, and unnest any expression that contains an identifier (except those after the last non-expression argument). Hence the predicate isPureExpressionWithoutIdent.
