you should use a mixin instead of traits that use strings to 
store references.
The issue with either is that strings in different contexts may 
not keep referencing the same thing. The mixin will just be 
smaller.

```d
void bletch(string field)(ref Foo s,int x){
     mixin("s."~field~"=x;");
}
```

if you want to be *idiomatic* you should figure out how to make 
an alias survive the compiler warnings for your use case and 
given I started an argument I suggest this is better and least 
prone to failure

```d
void bletch(alias f, string s)(int x){
     mixin("f."~s)= x;
}
bletch!(s,"bar")(2);
```
