An Alternative Implementation of Routines

In the current conventional implementation of a routine, a parent receives the outcome of its child. A parent may be coded such that it does not use the outcome of its children, thus allowing delegation an alternative implementation of the routine. As part of its execution, such a parent can replace itself by its children. The parent thus delegates the responsibility for its outcome to its children. In turn, a child may delegate the responsibility to its descendants. Due to such delegation, a routine previously dependent on the outcome of the parent thus becomes dependent on the parent’s children or on other descendants. Delegation is a variation on continuation a part of the Scheme programming language and of other functional computing. Delegation allows for a simple implementation of proper tail calls, non-strict evaluation, conditional items, streams and of other features of functional computing.
