## Generic-function: SB-SEQUENCE:MERGE
[![package](https://img.shields.io/badge/Package-SB--SEQUENCE-5f9ea0.svg?style=social&colorA=999999)](../) [![type](https://img.shields.io/badge/Type-Generic--Function-5f9ea0.svg?style=social&colorA=999999)](../#generic-function) [![clhs](https://img.shields.io/badge/CLHS-MERGE-5f9ea0.svg?style=social&colorA=999999)](http://www.lispworks.com/documentation/HyperSpec/Body/f_merge.htm) 

> Implements CL:MERGE for extended sequences.
> 
> RESULT-PROTOTYPE corresponds to the RESULT-TYPE of CL:MERGE but
> receives a prototype instance of an extended sequence class
> instead of a type specifier. By dispatching on RESULT-PROTOTYPE,
> methods on this generic function specify how extended sequence
> classes act when they are specified as the result type in a
> CL:MERGE call. RESULT-PROTOTYPE may not be fully initialized and
> thus should only be used for dispatch and to determine its class.
> 
> Another difference to CL:MERGE is that PREDICATE is a function,
> not a function designator.
