that is what it means, in D:

struct sqlite3_vfs {}
extern(C) {
alias RetRes = void function ();
alias DeclType = RetRes function (sqlite3_vfs *a,void *b, const
char *zSymbol);
DeclType xDlSym;
void zoo (void) {}
auto goo (sqlite3_vfs *a,void *b, const char *zSymbol) { return
&zoo; }
}
void main () {
xDlSym = &goo;
}
at least that is what i managed to decode, fed to C(++) compiler
and translate to D.
