 \CC~\cite{c++,ANSI14:C++} is an example of a similar project;
 however, it largely extended the language, and did not address existing problems.\footnote{%

 Fortran~\cite{Fortran08}, Ada~\cite{Ada12}, and Cobol~\cite{Cobol14} are examples of programming languages that took an evolutionary approach, where modern language features are added and problems fixed within the framework of the existing language.
 Java~\cite{Java8}, Go~\cite{Go}, Rust~\cite{Rust} and D~\cite{D} are examples of the revolutionary approach for modernizing C/\CC, resulting in a new language rather than an extension of the descendent.

+The problem is the name clash between the library routine \lstinline@abs@ and the \CFA names \lstinline@abs@.
+Hence, names appearing in an \lstinline@extern "C"@ block have \newterm{C linkage}.
 Then overloading polymorphism uses a mechanism called \newterm{name mangling} to create unique names that are different from C names, which are not mangled.
 Hence, there is the same need as in \CC, to know if a name is a C or \CFA name, so it can be correctly formed.
 There is no way around this problem, other than C's approach of creating unique names for each pairing of operation and type.
 This example strongly illustrates a core idea in \CFA: \emph{the power of a name}.
-The name ``©abs©'' evokes the notion of absolute value, and many mathematical types provide the notion of absolute value.
-Hence, knowing the name ©abs© should be sufficient to apply it to any type where it is applicable.
