--- Comment #1 from moonlightsentinel@disroot.org ---
Allocating slices by themselves is explicitly disallowed due to the ambiguitee possibilitly IIUC (you almost always want to allocate the actual array). run.dlang.io shows the degradation of the error message:

Up to      2.078.1: Failure with output: onlineapp.d(3): Error: new can only
create structs, dynamic arrays or class objects, not ubyte[]'s
2.079.1 to 2.090.1: Failure with output: onlineapp.d(3): Error: new can only
create structs, dynamic arrays or class objects, not `ubyte[]`'s
2.091.1 to 2.093.1: Failure with output: onlineapp.d(3): Error: cannot create a
`ubyte[]` with `new`
Since      2.094.1: Failure with output: onlineapp.d(3): Error: missing length
argument for array

The error message probably complain about the type + suggest adding a length (which should be the solution in most cases)

--- Comment #2 from Basile-z <b2.temp@gmx.com> ---
Isn't the issue more like a request to have a way to allocate the slice payload on the heap ? Maybe a druntime template should be added for that rare usage, e.g

```
auto newHeapArray(T)()
{
    import core.memory : GC;

    alias RT = T[];
    return cast(RT*) GC.malloc(RT.sizeof, 0, typeid(T[]));
}
```

better with calloc of course
