I think one of the things we don't appreciate enough about Rust is how it goes out of its way to say "hey! looks like you're trying to use a C idiom. Here's how we say that in our language." Anyway we spell `-1` as `!0`, which is something we may want to tell C programmers.

!0 is the worst way to spell it imo. Spell it u32::MAX

too many keys

Was this tweet using as few keys as possible to ironically make the argument that reducing the number of keys used in an expression at the cost of clarity and readability is a bad argument? If so I agree

taking off my jokes face, or as i guess you could call it, my "bit mask", i think `!0` and `uN::MAX` are each the best in their domains, but they are nevertheless in different domains. if you work with numeric integers, use `MAX`; if you work with bitwise registers, use `!0`

I do actually use `::MAX` in #bitvec, since constants can propagate through traits and literals cannot, but in my concrete code, `!0` more clearly indicates "a register with all bits set", while `::MAX` only indicates "an integer that cannot be exceeded"
