Aliasing a mixin (or alternative ways to profile a scope)

As a small addition, if you always want to pass the function name as a
parameter, you can simplify this to the following:

```
enum profile_scope(string name = __FUNCTION__) = "import core.stdc.stdio
: printf; printf(\""
    ~ name ~ "\n\"); scope(exit) printf(\"" ~ name ~ "\n\");";

extern (C) void main()
{
    mixin(profile_scope!());
    foo();
}

extern (C) void foo() {
    mixin(profile_scope!());
}
```
This will print
```
main.main
main.foo
main.foo
main.main
```
to the commandline.
