[[const]] is not const
Indicates the result is entirely determined by the arguments and does not access main memory in any way, including accessing members of this
This allows the compiler to easily elide/duplicate calls, because it doesn't need to consider aliasing at all when moving this function's body around.
WHEN IN DOUBT USE ein_pure, which is a much safer way to annotate pure functional code

[[pure]]
No side-effects other than return value, may inspect globals
Allows the compiler to easily elide/duplicate calls. This can freely commute past other operations that can be shown not to affect the memory locations read.
