I'm trying to rewrite really old D code. There was fragment like
that:
```d
template Foo(T, T[] Array) {
// ...
}
// ...
Bar[] arr;
Foo!(Bar, arr);
```
This gives error `can't read arr in compile time`. Small changes:
```d
template Foo(T, alias T[] Array) {
// ...
}
// ...
Bar[] arr;
Foo!(Bar, arr);
```
This is valid D, but it doesn't work. It gives error "Error:
template instance `Foo!(Bar, arr)` does not match template
declaration `Foo(T, alias T[] Array)`".
Of course, there is some ways to avoid this error (e.g. check
Array type in if), but I don't undestand why this code doesn't
compiles.
