// 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.
