In the code below, there is a two parameter function `foo` and

be a way to specify it at compile-time.
Have you tried [`std.functional.partial`][1]? Using it, your
example could be written like this:
```d
import std.functional: partial;
enum int a = 1;
alias foo2 = partial!(foo, a);
```

Thanks. This is basically equivalent to
```d
int foo(int a)(int x) { return x + a; }
alias foo2 = foo!a;
```
The downside is that you wouldn't be able to `alias foo = foo!a`.
Another approach would be to do something like
```d
int foo(int b = a)(int x) { return x + b; }
```
so that the default case could be handled.
