So true and so worth the extra knowledge to understand your tools. You should also read about the various knobs on your compiler or interpreter from time to time. I used to reread gcc manual every five years, and now I search on the env variables that affect
python runtime. Getting ready to that for go build chain now I have 3 or 4 production go things. Similar for my editor and libc and language stblib and kernel APIs, tho they are more diffuse than the gcc manual.
