byte* and int length -> byte[]

[mimocrocodil]

I obtain immutable(byte)* and int where contained length of bytes block from C 
library.

Can I convert this into byte[] without explict copying etc.

Something like:

byte* p; // bytes
int size; // size of bytes block

byte[] b;
b.length = size;
b.ptr = p;

// now b contains bytes from library
