 // Includes the core of LL, without any real features for client:

 // 

 // tuples, lambda functors, return type deduction templates,

 // argument substitution mechanism (select functions)

 // 

 // Some functionality comes as well:

 // Assignment and subscript operators, as well as function

 // call operator for placeholder variables.
