The amount of work it takes to maintain header files in #cpp is honestly absurd

Any #googlefi users out there notice service has been steadily degrading?

Sure is a drag writing going back C at work after writing #rustlang all weekend

And to think I almost gave up #moonBound

#sls please I’m getting sleepy
