Yeah, but maybe there's some arcane C# fuckery that does that

<@128154136020647936> Access the underlying buffer (there may not always be one, it's not a strong guarantee, but there usually is), get a fixed pointer to it and do your lookup in an unsafe block

Would do it that way personally because I already have plain c code that does it so with minor adjustments I can just copy/paste. Nice types are nice but sometimes raw pointers are just better.
```cs
fixed (byte* b = stream.GetBuffer())
return *(int*)do_weird_lookup(b);
```
For example

I mean you go with a dumb for loop or wrap around and use a binary reader around your stream but you'd kill performance since binaryreader has a small buffer and when you read byte[] it copies
