Such projects as Reselect and Re-reselect try to solve the task of memoization. But there is no standard solutions for some applied problems. This library was created to try to systematically solve the following problems:

• Work with optional objects as a source for selection.
• Binding parametric selectors to specific property values.
• Adaptation of parametric selectors to the new parameter interface (useful for creating parametric structured selectors).
• Using selection results as parameters for a new selection.
• Calculating the aggregate value from a collection of selector results.
• Structuring of selection results (more proper typed version of structured selector and cached structured selector).
• Implementation of key selectors composition (useful for key selector creator usages).
