  -----------
  Rewrite the mechanism of tuple parameter unpacking.

The previous way worked great if there was a body to append the unpack statements.
Unfortunately, tuple parameters are also allowed as parameters for  lambda
functions. lambda functions don't have a body where statements are allowed :(
=> No way to use the existing code.

The new way wraps the tuple unpacking into a single expresion, by using nested
lambdas. This expression can now be used wrap tuple parameters of lambda
functions.
