Would `%q` work? In reference to [token 
strings](https://dlang.org/spec/lex.html#token_strings ):

```
enum a = <something>;
enum b = mixin(format!"%q"(a));
enum c = mixin(q{<something>});

static assert(a == b && is(typeof(a) == typeof(b)));
static assert(c == b && is(typeof(c) == typeof(b)));
```
