I'm trying to create a series of function. There will be ten
of them, and they will be called `function_0`, `function_1`,
etc. However, in my example, "stringof" returns the character
"i" itself and turns that into a string instead of getting its
actual value (number).
Any ideas how I can achieve what I'm trying to achieve?
Great masters generally warn to stay away from stringof. Please
do not use it as much as possible. The following code snippet
will be useful to you:
```d
alias CN = __traits(allMembers, CardinalNumbers);
static foreach(i; CN)
{
mixin(create_fn!(i[1]));
}
enum create_fn(char num) = `
auto function_`~ num ~`()
=> "Hello from function `~ num ~`!";
`;
enum CardinalNumbers
{
n0, n1, n2, n3, n4, n5, n6, n7, n8, n9
}
void main()
{
assert(function_9() == "Hello from function 9!");
}
```

If count < 10 then why not just
```d
import std;
static foreach(c; "0123456789")
{
mixin(create_fn!(c));
}
enum create_fn(char num) = `
auto function_`~ num ~`()
=> "Hello from function `~ num ~`!";
`;
void main()
{
assert(function_9() == "Hello from function 9!");
}
```
