'f' above is local, and the compiled program works as expected. Can't see why
making it a template should affect the semantics. Also, if the following didn't
compile, the whole "pass functions by alias" business would go down the drain:

void bar(alias f)() {
    f(1);
}

void main() {
    int y = 1;
    alias f = (x) { y += x; }; // local, equivalent to "void f(A)(A x) { y +=
x; }"
    bar!f(); // ok        
}
