Whoops, I though that answered this.
So way back when Joe and Mike and I were working for the Ericsson Computer Science lab. The lab had a Dec VAX running Berkeley unix. It was actually the first VAX and first unix that Ericsson had. Anyway I was browsing through the bsd unix code and, while most was written in C, there was one long section written in VAX assembler which iirc had to do with process management and context switching. It was basically just page after page of assembler totally without comments. EXCEPT for somewhere in the middle their was ONE comment “And now for the tricky bit”.
I thought this was funny and use it myself sometimes in my code, though I do actually comment my code.
