I mean, https://dlang.org/spec/declaration.html#extern doesn't offer any
function examples and it states: "The primary usefulness of Extern Declarations
is to connect with global variables declarations and functions in C or C++
files.". But  I don't see how extern (not extern(linkage)) is used to do that.
