Please provide an example of an API for extension functions n this
case, in Java or C++..

Concise definition in Haskell does not correspond to a concise
implementation universally.  
This is introducing a whole new concept of function objects and abstract
interfaces, and for all places - in Target match..  For the case that can be
solved using much simpler approach - either runtime sequence size check (you
DO get you sequence in runtime anyway, so what we have is just sugar coating
it for abstract academic reasons anyway)
