First of all, thank you for a wonderful library Eric, truly a joy to use 🤗

I am building a project using the newest version of range-v3 that gives me a bunch of warnings related to the deprecated flag.

My compiler is a s follows

➜ software gcc --version
Apple clang version 15.0.0 (clang-1500.0.40.1)
Target: arm64-apple-darwin22.6.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin

Example of warnings...
