My purpose for the case sensitive remark was that environmental variables are not case sensitive in Windows.

Re: How to read a particular environmental variable?
You might want to take a look at Trait::Env, partly because I've not tested it in Windows and I'd be interested to know if it works well.

My guess is the impact is exactly the time it takes for your cpu to perform the initial context switch for the syscall, and then another when waking up. Hi Paul, I opened the resource monitor and watched the CPU load: raku -e "say 'start sleep 10'; sleep 10; say 'stop sleep;'" start sleep 10 stop sleep; Nothing. Sleep must be recovering using a system interrupt. Yippee! -T This is what I was afraid of. The old fashioned batch programming wait 10 seconds: >ping -n 10 -i 10 8.8.8.8
