Worth noting that you *can* write
```d
alias foo = partial!(foo, a);
```
...which will add the partially-applied version to `foo`'s
overload set.
You sure about that? Below fails to compile on godbolt with ldc
1.27.1 [1]. For some reason run.dlang.org is just hanging...
```d
import core.stdc.stdio: printf;
import std: partial;
int foo(int x, int a) {
return x + a;
}
enum int a = 2;
alias foo = partial!(foo, a);
void main() {
int x = 2;
int y = foo(x, a);
printf("the value of y is %i", y);
auto z = foo(x);
printf("the value of z is %i", z);
}
```

If there is only one possible value for the overload, is there
an issue with using default arguments?
```d
int foo(int x, int a = 1) {
return x + a;
}
void main()
{
import std.stdio:writeln;
writeln(foo(5));
writeln(foo(6, 7));
}
```
