@lambdagrrl Yes, display logic, where all logical rules follow directly from polarity.
@lambdagrrl Yeah, there is :)
@lambdagrrl Oh, woops, did I mess that up? The branching rules were meant to be listed as interesting. Though the boring rules are actually the non-invertable rules, whereas the others are invertable, so there's a good argument for flipping the boring/interesting distinction.
@lambdagrrl The one looks boring, the other doesn't, but they both follow directly from the polarity of the connective, so I guess they're both kinda dull.
Gotta say, very much a "do as I say, not as I do", 'cuz I use a *lot* of TeX packages, and I've never acknowledged their authors. Gonna give it a shot in the future! :)

@lambdagrrl she got distracted, sorry
@lambdagrrl tell that to my lack of impulse control
@lambdagrrl my mishaps are more of the "drops knife" or "dries knife" or "dances with knife" variety.
