  • I have bad news for you

  • At my previous workplace we had a C macro that was something like

     c
        
#define CheckWhatever(x__, true__, false__) \
    whatever(x) ? (true__) : (false__)

    I don't remember this shit, so I'm just paraphrasing cursed C. The question one would ask is... why? Well, because you also want to do

     c
        
#define CheckWhatever2(x__, true__, false__) \
    CheckWhatever((x__ ##1), (true__), (false__)) \
    CheckWhatever((x__ ##2), (true__), (false__))

    And, of course

     c
        
#define CheckWhatever3(x__, true__, false__) \
    CheckWhatever2((x__ ##1), (true__), (false__)) \
    CheckWhatever2((x__ ##2), (true__), (false__))

    Long story short, someone wanted to CheckWhatever6 inside another macro. While debugging code old enough to vote, my editor suggested expanding the macro, which expanded to ~1400 lines for a single ternary operator chain. Fun times!

    • Why is working class called working class?

  • From the article: The proletarii constituted a social class of Roman citizens who owned little or no property. The name presumably originated with the census, which Roman authorities conducted every five years to produce a register of citizens and their property, which determined their military duties and voting privileges.
