# In Rust 2021, the bodies of `unsafe fn` may use `unsafe` functions themselves without marking
# them.  This is an overload of the word: `unsafe fn` is documenting something for the caller, but
# that doesn't mean the entire function body is unsafe.  Denying this lint (which becomes
# warn-by-default in Rust 2024) means `unsafe fn` bodies still must use `unsafe {}` like normal.
