Is there a way to slice non-array type in @safe?

Yes, I'm aware, there are no pointers in the code. The pointer 
was used
here because it was the only way to solve the problem (but not in 
@safe).

I want to make an array of bytes that has the bytes of the value 
passed.
For example, if T = int, then I want an array of 4 bytes that has 
the 4
individual bytes of `s1` let's say. For long, an array of 8 bytes 
etc.
Ideally, that would work with `ref` (i.e. the bytes of where the 
ref points to).
