Both Issue #14758 <https://github.com/rust-lang/rust/issues/14758> (Specify that int and uint are at least 32 bits on every CPU architecture) and Issue #9940 <https://github.com/rust-lang/rust/issues/9940> (rename `int` and `uint` to `intptr`/`uintptr`) call for RFCs.
So RFC https://github.com/rust-lang/rfcs/pull/161 summarizes those discussions, explains the core issue of code portability to CPUs with smaller address spaces, conceptions and misconceptions about int/uint, what's a "default" integer type, and proposals including coding style for integer sizing. Let me know what you think. -- Jerry
