Discussion on: Type/pointer cheatsheet

I'd think it's because there's no concept of optional values in C, yet optional pointers can be represented in the same amount of space (using 0 as indicator for a null pointer), whereas optional non-pointer values take up extra bytes, e.g. a ?u8 is actually 2 bytes, a ?u16 is 4 bytes, a ?u32 is 8 bytes...

An argument could be made that by that logic slices shouldn't be supported either (but they are), so I really don't know the reasons... :)
