In the code below, foo!fabs compiles without issue, but
foo!"fabs" does not because the import is not available in the
string mixin. If I move the import to the top of the module, then
it works. However, then if I move foo to another module, then it
will no longer compile since it is in different modules.
Is there any way I can make sure the mixin knows about the import?
I am just using fabs as an example. Ideally, I would want to use
any function from any other module. I can figure out how to do
it, for instance, if the only functions that were allowed were
those in one module, like std.math.
```
double foo(alias f)(double x) {
return f(x);
}
template foo(string f) {
mixin("alias foo = .foo!(" ~ f ~ ");");
}
void main() {
import std.math: fabs;
double x = 2.0;
double y = foo!fabs(x);
double z = foo!"fabs"(x);
}
```
