'''Substitution failure is not an error''' ('''SFINAE''') refers to a situation in [[C++]] where an invalid substitution of [[Template (C++)|template]] parameters is not in itself an error. David Vandevoorde first introduced the acronym SFINAE to describe related programming techniques.<ref>{{cite book | last=Vandevoorde | first=David |author2=Nicolai M.
