12// Includes the core of LL, without any real features for client:
13//
14// tuples, lambda functors, return type deduction templates,
15// argument substitution mechanism (select functions)
16//
17// Some functionality comes as well:
18// Assignment and subscript operators, as well as function
19// call operator for placeholder variables.
