Right now, I've been implementing classes separately, and I
need a dummy symbol. The best world is not even having a symbol
but having only its implementation, for example, I would like
being able to do that:
```d
void pragma(mangle, "test")(int a){
writeln(a);
}
```
Is it possible somehow to do that?
You can use the following string mixin to generate an identifier:
```d
// Mixin to generate a new identifier that won't repeat within a
scope
enum gensym(string prefix = "_gensym") =
`"` ~ prefix ~ `" ~ __traits(identifier, {})["__lambda".length
.. $]`;
```
But since D currently doesn't support mixing in only a function's
name, you'd have to put the entire function definition inside a
mixin:
```d
mixin(q{void pragma(mangle, "test") }, mixin(gensym), q{(int a) {
writeln(a);
}});
```
