> 64-bit address space. Memories and tables can now be declared to use i64 as their address type instead of just i32.

Could be nitpicking but in the PDF (https://webassembly.github.io/spec/core/_download/WebAssembl...), there's a passage that says:

> 32-bit integers also serve as Booleans and as memory addresses. (under 1.2.1 Concepts)

While 64-bit is not mentioned. Could it be an oversight or I understood it wrong?
