This is simplified code that illustrates the issue I've faced:
```d
struct A(T) {}
alias B(T) = A!T;
void f(T)(B!T b) {}
f(B!string.init);
// Error: template `f` is not callable using argument types
`!()(A!string)`
//f(B!string.init);
// ^
// Candidate is: `f(T)(B!T b)`
//void f(T)(B!T b) {}
// ^
```
I know that I can do `alias B = A` in this specific example, but
in the actual code, I'm trying to do `alias B(T) = A!(H!T)` which
leads to the same error:
```d
struct A(T) {}
struct H(T) {}
alias B(T) = A!(H!T);
void f(T)(B!T b) {}
f(B!string.init);
// Error: template `f` is not callable using argument types
`!()(A!(H!string))`
//f(B!string.init);
// ^
// Candidate is: `f(T)(B!T b)`
//void f(T)(B!T b) {}
// ^
```
