> Currently we use {{functionsForEval}}, {{NamedLambdaVarible}} s in which are replace with of arguments from the original functions, to make sure the lambda variables refer the same instances as of arguments, but it's pretty hacky.
> Instead, we can use a global map and set/get the lambda variable values in the map.
