I just remembered and was excited to finally use std::format only to 
find that it isn't available in GCC.  Even the example code on the 
reference page fails to run: 
https://en.cppreference.com/w/cpp/utility/format/format. :)

I couldn't find anywhere that GCC has plans to include std::format. 
Does anyone know if or when std::format might be added to GCC?
