It's a strange omission. There are hex and binary literals, but no octal!

Proposed syntax: 0o432

An octal! macro would be equally acceptable.

Meh, closing, not important.

Please reconsider this feature request; Unix permissions are most easily expressed using octal permissions.

While expressing permissions via binary 0b111_101_101 is workable, I suspect most of us would do the mental arithmetic to re-write that to 0o755. Clever macros can mask some of this -- see e.g., https://gist.github.com/kmcallister/7312179 -- but asking each chmod() or umask() user to either re-implement them or discover and import such a package feels awkward compared to supporting 0o ... syntax directly in the language.

Thanks

Associated with Issue #6563.

Useful for Apollo Guidance Computer simulation, Unix file system permissions, and maybe one or two other things.

Re-write shadow lints

changelog: Move shadow_unrelated to restriction
changelog: The shadow lints find a lot more shadows and are not limited to certain patterns

Drastically simplifies the implementation. Catches a lot more cases.

I removed the "initialization happens here" note. It is not helpful IMO.
